Paying with food/drink from chipstack

Just curious - I always thought this was a black or white issue, where rooms that serve food/drinks either allow it to be paid from via chips from a player's stack or not, and there were no limits on how much/often one can do so. Accordingly, I've never heard someone grouse about this, or if they did it was due to not being familiar with the rule.

But recently there was a guy who, in the course of 2-3 hours, probably dusted off $75 from his stack via drink orders (paying $10 a pop) plus a couple of food orders for even more. After the guy's second food order someone said "enough is enough - you're taking money off the table that we have a right to win." The guy replied that the rules say he can pay that way, and that's what he's doing so if they have an issue they should take it up with management.

What are people's thoughts on this? Are there examples of this indeed being a gray area, where it could depend on how much/often someone does this?
