To the asshole at Mr. Sub

I know it's frustrating to not be able to get what you want when there's a giant poster advertising it.

But when someone apologizes and tells you it's not available because that's a breakfast item and not available in the afternoon, your options are:

a) leave.
b) order something else.

The following option, which you exercised, should be deleted from the list of possibilities:

c) scowl, badger the employee for five minutes straight - while a line forms behind you - until she makes up a reason why what you want is unavailable, force her to make a meatball sub with only meatballs and cheese (and they have different cheeses, so naturally you get angrier when she asks you to specify what kind *gasp* THE NERVE!), then when she goes to ring up your order, you shove the sub back at her and say, "HERE! I'm not going to eat this SHIT anyway because YOU didn't have what I wanted so YOU eat it!" then slam down your tray on the counter and stalk over to another food stand and glower at their employee, who has no idea what's going on.
