I am actually up all the drinks I got comped in Vegas. I sit down at the penny slots and bet one penny one row until I get offered a free drink. I tip the server $3, bet two more pennies for good measure, get up, and walk out with the drink in my hand. I just got like a $3.10 Manhattan for walking around the strip, including tip, courtesy of some business that was low-key trying to scam me and deserves to have less money than they do.
I worked in the bar business and know what a shot of rail bourbon costs with a volume discount, and the ten cents they get from the slot machine definitely does not cover it. I’m happy to give the server $3 for their effort.
They’re obviously doing it because it’s profitable. If they were being genuinely altruistic, I’d be much less likely to take advantage of it.
