If you read my pervious posts. Even at top end hotels like a Ritz tipping is not and was not common.
Also I've known people who worked in housekeeping. The rate of thier pay way always proportional to the room rates of the hotels. 2 star was getting minimum wage, 3 star about a dollar more, 4 star about 3 dollars more, and 5 star was getting about twice minimum wage.
Consider this before you pitty the low wages of housekeepers. Where else can someone get a job, with no previous working experience, little education and not know the native laungage but still make twice minimum wage?
Oh please. The data available for salary averages doesn't support your friend's claim, at all. If you don't want to tip, don't tip. But your implication that maids in the hospitality industry are somehow, miraculously making twice the minimum wage is insulting. Even if that were true, how many 5 star hotels are around DLR? You don't feel the need to tip, fine. In the mean time, I will go ahead and take "pitty" on these people picking up garbage, cleaning up puke and scrubbing toilets and throw them an extra buck or two.
