Older Ladies

So, I get a table of older ladies and they ask me, "Honey, how much is your coffee?" I tell them that it is $2.19. One of them says to me, "Lord! That's expensive. That would've been your tip! So, I'm like great. Well, now I get to wait on a table that I know I am not going to get a tip from. Not only do I not get a tip from them, they sit at my table for almost three hours!
