Saphan Kwai have adopted double pricing
In recent trips to Saphan Kwai, last 3 trips or so, I have been quoted 2 k ST plus room 300 to 500 from various shops like T ded, Rainbow, Chat, For you, Bai Tong ect, but before that for years, it was easy to get 1. 5 k-2 k with a room voucher. I was not too sure about the recent price hike. This is a very local hunt ground for ordinary somchais, I just don't really believe average somchai pays 2 k ST, plus room plus food and drinks, and pretty much near 3 k for a ST session for an ordinary Thai man.
I was chatting with a friend from decent playboy last night, who is long term expert in Saphan Kwai, he told me the things I suspected, recently the big increase the number of foreign tourists in this areas namely the Japanese, these shops have developed a double pricing. They have somewhat standardized 2 k short time rate for tourists or 2. 5 k with hotel voucher in some shops.
He could confirm that the ordinary Thai customers are still paying 1. 5 k plus room, and the shop regulars are still paying 1. 5 k include room for years now. So just keep in mind about the recent double pricing when visiting this areas. You can try to bargain down but may not work anymore.
