They used to be in Bangkok too, maybe 10-15 years ago. Remember having dinner with a date in an open restaurant and one of those pushy kids would come and repeatedly tug on my sleeve:
"Mister, buy flower for lady."
"No."
"Cheap Charlie!"
I look at her grimed face: "Dirty Diana!"
She gave me a most bewildered look and left...
Haven't see these little tykes for ages.
