It really baffles me how unaware customers are about the people that are handling their food.
I understand not catching or forgetting a name when trying to find your server, but I (small, mid-20s), have been mistaken for a woman half a foot taller with forty years on me!
It's always a double-take or a flashback to a server dream when someone randomly asks, 'where's my refill?' and you're thinking, 'oh Lord, are you my table? Wait..'
The one that really bothered me was when someone confused me with one of my good friends. Granted - we're around the same age. But I'm taller, blonder. And the confusion in question was 'hey, aren't you the one that just had a baby?' Do I LOOK like I just had a baby?!
