I don't tip maids, taxi, food folks in China. But for 15 years at good China hotels, I do tip conseiquer and lead EL staff. Repeat visits and long stay service is very worthy for me. Discovered early on a high turnover rate in these areas, so also may need to tip the assistant, or other lead EL staff. I 'never' wait "10 minutes" for a room or a good beverage on repeat visits.

I'll be in Los Suenos Costa Rica for the Signaturetriplecrown fishing tournament week in mid January. (Mariott resort club marina) If i only tipped $100 a day there, I would be considered a stingy cheapskate in "Latin' culture. BTW, best San Jose CR airport hotel is the Sheraton Casino. Fabulous 8th floor EL open 7 days a week, No tips = no food, no table on a 2nd visit. (The conseiquer is the same guy for the last 10 years)
