The most obnoxious barman EVER
Stayed here for a week starting on 28th Jan 2012. First evening at the bar there was a very lovely oriental lady. Very professional and courteous. 
Second evening she was replaced by a 50ish year old American guy. Right from the start I found his attitude disturbing. He was clearly friendly with another guest who was already seated at the bar and was trading opinions about all sorts of subjects.
'I hate people who ask me whether the beer is cold' was one statement he made shortly after a person came up and asked him that question. 'I hate it when people ask me "are you open" ' was another statement he made. He then made the bold statement 'I hate British people'. (I'm British, a fact that he must have figured out when I ordered my beer). 'I hate the British. They never leave a tip, and don't tell me they don't know that tipping is customary in the US. They always pretend that they don't know. They know alright. They're just cheap and dumb'.
I sat there with my mouth open thinking what the hell ?
I few minutes later a couple of old ladies came and sat at the bar. The barman saw them but needed to move away from the bar for a couple of minutes and told them he'd be right back. 
True to his word he was back in a couple of minutes but decided to serve his friend from earlier BEFORE serving the 2 old ladies. He then went off to run another errand. By the time he came back the ladies had gone.
They returned later with the duty manager. They'd clearly complained and the duty manager bought them a couple of glassed of red wine on the house. 
Just a few minutes later the barman noticed a couple of very large ladies heading towards the bar area. Immediately he said in a loud voice (but not loud enough that the ladies would hear), 'Holy Guacamole. Thank god we haven't got an all you can eat buffet here' to which his friend at the bar responded and they then went on to make disparaging remarks about the over-weight ladies. Of course when he went over there to get their drinks orders he was all smiles but back at the bar he continued expressing his opinions about large ladies.
I've been around a bit. Stayed at hotels all over the world but this was THE WORST barman I've ever come across. I complained to the hotel but they just asked me to email more senior people which I will get around to doing eventually. I eventually left the bar. I also made it a point to mark on the bill a tip for a grand amount of $0.00.
