My only beef (pun? I don't know) beyond the usual "blah blah they fucked up my order blah blah" is with Krystal.
They have a #5 which is 3 Krystal Chicks. They have a #3 which is 5 Krystal Hamburgers.
Now, I have no problem with this. But they do. 2 occasions:
1:
"Can I get a #5 with..."
"Did you want the 3 Chicks or the 5 Krystals?"
"Uhh... The 3 Chicks. Isn't that the number 5? Did I say 5?"
"Oh, yes, you did, but some people get that confused."
"... Oh?"
2:
I ordered the #5 and they gave me the #3, because apparently it's confusing. >_>
