Same in a restaurant. A friend was openly asked by the waiteress if after the venue closed, would he have liked some sensual company at his place.
For me, it also happened with a female Grab driver. She did not directly offer of course, but after the regular BS questions during the ride...how long u here-u married-you own your house bla bla bla.....once arrived, there she was saying "I finish now my day and not sure what I will do for the rest of the evening".
So nope, it's not uncommon and Nope, it's not because I or anyother is bashfully good looking...it just for our ca$h. Once aware of this, you take it or refuse. Simple.
