Bacon in Britain (as opposed to ‘British bacon’ which doesn’t mean anything to someone British) comes in all manner of different thicknesses, smoked and unsmoked, back and streaky. The type which looks round rather than chop-shaped we would call ‘bacon medallions’ and tends to be eaten by those trying to pretend they are on a diet. This link to Sainsburys gives a good picture of the vast array of bacon available at the average large UK supermarket.
Yes, but, when I was in Texas for the first time, I found out that Texans don’t call “Texas Toast” “Texas Toast”, so one can’t automatically assume anything. LOL
When I lived in the Dallas area, I regularly saw thick-sliced bread at grocery stores labelled as “Texas Toast” type bread. Haven’t seen that since I left Texas 15 years ago.
Well, that’s what a Texan told me. He went on to say that, when someone like me uses the phrase, I am immediately seen to be an out of state person who doesn’t know any better. Shame on him! LOL
Lived in the Dallas area until a couple of years ago. “Texas Toast” refers to very thickly sliced and heavily buttered … well, toast. But it doesn’t fit in a standard toaster … that is, yanno, just plain toast.
But the term is used in Tx. Don’t know if your acquaintance was misinformed, or pulling your leg, or perhaps its a regionalism. TX is a big country, after all. 
I’ve seen “Texas toast” in supermarkets outside Texas.
You can definitely buy Texas Toast in the freezer section in Texas. HEB had their store brand and they also sell Pepperidge Farms brand.

ETA, my first hand experience is in the Austin area, which is of course full of not-real-Texans.
Probably the champion candy for pulling out fillings (second place: Mary Jane). I think I lost two of them before I stopped eating it.
I loved Turkish Taffy, but I never chewed it. I just sucked on it and let it dissolve in my mouth. Sad to hear it’s no longer made. 
We have loaves of “Texas Toast” here in Canada. Like “American Cheese” and “Swiss Cheese,” the name of the product doesn’t necessarily tell you where it’s made.
Aside from the slices being thicker, how does “Texas Toast” differ from run-of-the-mill white bread? Do Texans have a special way of toasting their bread?
Cattle brands
Isn’t it normally slathered in butter and grilled on the cooktop, as opposed to just thrown in a toaster?
As it is too thickly cut to fit into a standard toaster that would be the typical way to toast it. It can be grilled or toasted in the oven as well but a flattop/griddle is the more common
