Would this be lame, cool, or +EV?

I live in a big, 5 bedroom house. I am 20 years old and go to college. We have people over 2-3 times per week to play poker, beer pong, or just to drink.

What if I would buy an old, cheap vending machine and put Busch Light in it at $0.75 per can. You can buy a 30 pack for ~$16, which is about $0.50 per can. Thats a pretty nice profit IMO since we've gone through over 5 30's in a night. I could just have tons of $1's on hand because I think investing in a quarter machine would be too expensive.
