Oh the dreaded "tipping" issue. I'm afraid I am a Brit who tips according to how good an experience I've had. I had SUCH a good experience at Harvest Bistro restaurant at Hilton Bonnet Creek hotel where we were staying last time that I left some ridiculously high amount because it truly was deserved but on the other hand, I had a ludicrously bad experience in the same place a few days later so I didn't leave a tip at all. I know it's not the done thing esp in the US but I think if you can't be bothered doing a job properly then you don't deserve anything on top of your wages.
