Waitresses make me think I'm going insane.

I went to Tully's yesterday to watch some basketball and have a few drinks. Things were going ok, they were screwing up orders a bit, but otherwise it was going OK. I ordered a grapefruit and vodka and continued watching the game. The waitress comes back a few minutes later with a drink that was red and yellow. I tasted it and it was just cranberry and grapefruit juice with no delicious nutritious vodka. I politely notified the waitress of this error and thought I would get a "whoops my bad" or something like that. Instead she said I ordered exactly what she gave me. I hate when this happens because I start to think that I'm losing my mind because I apparently gave back what I asked for. You ask the people around you and of course they do not know because they're doing their own thing. She didn't even bring me back what I originally asked for. She just added vodka(I think) to what I already had. I guess dumping 5 cents of juice was not worth the effort.
