Last night, I was at Lucky Boys. Called for bill and paid 750 baht for my drink and boy off fee with a 1000 baht note. I was seated with a mamasan who had served me the past 2 nights. Waiter came back and another mamasan also appeared. This particular mamasan would come and sit next to me occasionally (usually when the younger mamasan was away with other customers).
He made the usual small talk - “where are you from? How many days you stay?” and throughout the night - “which boy you like?”
