You'd have thought I'd have insulted their family. I had multiple people become indignant with "I'm a poor college student! I can't afford that! No way! Do you know how expensive school is?!?!". They're paying at least $3/night on coffee minimum anywhere they go, and often more.
EDIT: quick followup to a bunch of answers. I'm not sure I said it was completely irrational, but... weird. This was just in the last several years - people are paying $400+/credit hour, and using credit/debit cards for everything. Yes, I remember only having a few $ in my pocket, back when the world lived on cash, and conserving every dollar was of the utmost importance. Charging people $1/night... inevitably on a card... nets you about .70c. My point was to try to at least break even, and provide a service to some folks. Making $4/night from 5-6 people, then spending $5 in coffee/tea/snacks... I'm losing money. I guess if I made it up in volume and sold it to a VC, I'd have been rolling in it. As it was, I didn't. It was an idea I floated by people, and it was not received well.
Thank you for the responses.
