Last night I went to the Bangkok <deleted> Club to see a movie. I purchased two ice creams for around 300 baht and gave her a 1,000 note. She pulled 400 baht out of the till and made a sign that she had no change and would get some. I offered her 500 baht instead which she refused and went out the back to change my 1,000 baht note. When she returned she gave me 200 baht change. I said I gave her 1,000 baht but she denied this. My gf, who hardly speaks English, when I complained kept telling me she says you only gave her 500 baht. My gf was not there when I handed over the 1,000 baht note. In the end I gave up and accepted only 200 baht in change. I was really pissed off with my gf as she did not want to make a fuss.
To cap it all, when I went to the BTS on the way home and needed to top up my card he said I needed to produce my passport, a new rule. Was I pissed off by this time.
