As you have already stated, you like to leave tips for good service. And, as Mardhi says, if you tip, you're gonna get good service next time. Thailand is very much a commission based economy, and if you don't tip or pay commission, you aint gonna get service or anything done.
Agreed.
However, as the process begins with the customer's first impressions of a bar, it's staff and the quality of service then the customer would possibly not return at all if the service was particularly poor or they encountered pushy or rude staff. This could result in the subsequent experience of receiving poor service for a low or no tip never being known as they wouldn't return. In effect, a lost customer.
The vast majority of customers, I hope, would be capable of seperating the poor or rude service of one individual staff member from the overall atmosphere or vibe of a bar and would likely not base a boycott on one incident or person, which is just as well in many cases. But repeated poor or rude encounters with a particular individual can have a lasting effect, such as the ex-Strings service pig.
We could put the salaries up, and raise the drink prices-what do you think will happen, DC?
A bar with higher prices compared to competing bars may cause custom to move elsewhere. In Phuket the two week millionaires will most likely be blind to any increase as there is little or no ladyboy bar competition. But in Pattaya customers could easily go elsewhere and probably would if the price rise was significant.
In any case, if the quality of the girls in regular attendance is high then customers will return and turn a blind-eye to certain failings in individual attitudes and simply avoid encounters with those they find rude or irritating. I imagine the majority of us fall into this category, should any of the above arise.
