Any business with a superfluous A or string of A’s in front of its name goes right on my Do Not Patronize list. If being listed first in the phone book is that important to you, I somehow doubt you’re gonna be the sharpest tool in the proverbial crib at whatever it is you do.
I’ve always thought Blackwater was a particularly portentious name of a mercenary company that carries out murky and sometimes covert military-type operations.
The first time I saw it here in Panama, the Dago Restaurant made me do a bit of a double take. Of course, Dago is a nickname for Diego, and I guess the owner was unaware of the meaning for English speakers.
I also think the Chinese owners of the Fukin and Don Kee minimarts are unaware of the English meanings.
I went by a running shoe shop in Copenhagen, called Athlete’s Foot.
Peoples Natural Gas springs to mind.
I’ve got an old National Lampoon book full of photos of this stuff.
“Analtech” was another one.
One here in the Bay Area is Sheedy Construction - they do a lot of work in SF. The jokes write themselves; “We do a Sheedy job!” “Sheedy workers, Sheedy materials!” etc etc.
Also in SF is the Schindler elevator company - every time I see their trucks all I can think of is “Schindler’s Lifts”. 
Not exactly a bad business name but a horrendous advertisement was from a company called “Brains” that made a meat product containing pork. The name of the dish is a “faggot”. There’s a picture of a big poster at a railway station in the UK (IIRC) which proudly proclaims:
“It takes Brains to make faggots so full of pork!”
That’s a national chain of stores here in the US. I’ve always thought it was an unfortunate name too, but apparently it hasn’t been an obstacle to success.
I think it’s an apt name, myself. A little difficult to spin once they get attention on Capitol Hill and all, but still.
There’s a high tech company called Mindtelligent. Try to pronounce it. I dare you.
Over on the Peninsula there’s a street called Alameda De Las Pulgas. On this street is a restaurant called Flea Street, which is a translation of the street name.
That’s sort of what I meant, in the sense that you wouldn’t want a company name that cast a portentious shadow on your company at any time.
I’m sure that I’ve posted this before, but back in the early '90s, there was a restaurant down in the Strip District in Pittsburgh called My Dung. It’s no longer in business.
There used to be a fast food place here in the Dominican Republic with the unfortunate name of ‘Deli Bely’, and when I see the sign for a lawyer called ‘Manuel Labour’ I can’t help wishing that young Manuel had chosen another profession, like construction.
Any company named “Acme.” I always think of Wile E. Coyote and a lot of products I’d never buy.
Having worked for an Acme, I have to say that most of those companies are, like Ayds, victims of circumstances, having had the name long before 1949, when Chuck Jones did his first Road Runner cartoon.
Though I can’t deny the association is universal. (And it helped that the Coyote never wanted boiler water treatment chemicals…)
LOTS of Acmes out there. In one of the first on the list, the founder says he was a big fan of Wile E. Coyote.
Ah yes, and this one’s good, too.
Not terribly far from here is a business named Just Oil and More. It makes me irritable every time I pass it.
My pet peeve is businesses that Use " 'n " instead of “and,” as in Tires 'n More.
There was a store in my hometown called OK Wigs. Has there even been a less inspiring store name? Yes, we have a whole store of just wigs, yes it is not 1965, yes the wigs themselves are mediocre and do not deserve superlatives. Come in before we kill ourselves.
We used to have a car wash that boasted a brushless, 100% human car washing experience. It was called *The Hand Job.
I thought a law firm whose web address was http://www.mofo.com/ would have rated higher in this thread. It’s a personal favorite, but not in the league of some of these others.
Would you want to ride on the Who gives a sh*t, anyway monorail?
