checked into this hotel 500 baht a night plus 200 baht key deposit

when i checked out the receptionist rushed to my room stripped the bed come back to the office and laid all the bed sheets out on the floor, after about 20 minutes examination pointed to what looked like a very small 20 year old brown blood stain then told me no return deposit, after some arguing decided to return 100 baht of the deposit, this stain must be raking in a small fortune

You should have gone and got a black coffee and said to her " You call that a stain, tip the black coffee over the sheet and said now lady that's what I call a stain, you can keep the 200 baht, bye-bye."
