Where do you get a lot of assorted change at 4:30 on a Saturday?

Aaargh!

So, I’m working the door at a local music venue tonight.
I’m generally expected to bring my own bank from which to make change for folks coming in and paying the cover. If I don’t bring a bank I can get change from the bartender, but she isn’t usually in a position to help much- and any help she can give just makes things harder for her.
So, it’s almost 5:00pm on a Saturday and I just realized that I forgot to swing by the bank today to get a bunch of singles and fives.
Where can one go to get lots of change besides a bank???

Service desk at a grocery store? Mine’s always willing to crack a $20 for me, so maybe you can get enough cracked to make your bank. Otherwise you can drive around to a few different stores. Worst comes to worst you can make some small purchases at various stores and ask for your change in singles and fives.
