Hmmm Is it really that common to up a few times in short span of an hour or so? I haven't encounter b4 lah tbh. Usually the Rates change between days or at least maybe every few hours. Not like theirs from 13.00 to 13.018 to 13.03 within 1+hour. All other shops were 13.03-13.04 all along. Just felt cheated. Hahahaha.
They attracted the lunch crowd to their line and up their rate when nearing their turns. U don't see other shops doing the same. I left n changed at other shop anw.
Anw, no biggie. Which was y I deleted my original post, bt u quoted it at the same time. Hahaha.
It's not common but it can happen when currency fluctuates quite a bit and the market direction is unclear, so the money changers have a very limited margin for error.

too bad i was alone till my fren back, else i wld hv left when my fren told me another shop rate similar. only saw the rate changed when nearing my turn...
