I've often wondered why tipping is so expected in restaurants, but no longer in the accommodation industry. Restaurant workers get a described job with a baseline wage. Accommodation properties can be cheaper than dinner for a family of 4, and the money covers a lot more time.
The extra service given in a 'housekeeping' resort scenario is rarely rewarded. People who forget towels, pillows, matches, want romantic candles, have extra life jackets thrown in, have visitors arrive without notice having told them to drive right past the stop and register sign at the office and straight to their site/cabin, get messages from home that are relayed in good time by foot traffic...
Also if there is breakage, or someone can't be bothered to tidy up, it would be sensible to leave at least a token offering. Mostly I want to know about breakage to properly equip a cabin for the next occupant. Rarely is there a charge for "accidents", unless it is something big. I prefer to be told instead of discovering a problem.
I hope tipping becomes fashionable again.
