[ In 2015 we stayed at the Poly for 21 nights. For the first week we left a tip every single day but we were getting increasingly dissatisified with the service. They were having renovations done and there was a thin layer of dust over EVERYTHING. Coffee machine, pictures on the wall, TV, drawer units. My son has asthma so we politely asked at reception to have the room 'deep cleaned'. It never happened. We asked maybe, 3 or 4 times. At one point a manager came over to the room and agreed it was not acceptable. Even after the stay was over the dust was still there. Should we have dusted it down ourselves? I'm not sure. The whole room was pretty dirty. Anyway, we had a brilliant stay but after 10 days I stopped leaving a tip. Is that acceptable? I felt i'd paid more that enough to stay there and expected top notch service.[/QUOTE] I tip for GOOD service, and if it is not good I don't. I think it is perfectly acceptable to not tip for poor service. In my mind a tip is appreciation for a job well done, not a mandatory supplement.
