And it still bothers you.

Just making an observation. If that's okay with you.

It is one one-baht stamp for every 80 baht spent.  More on certain promotions.  (Last time they did the stamp thing, it was one one-baht stamp for every 50 baht spent.)

I once bought smilar stuff as the person who was Thai in front of me had at 7-11 and she got her stamps. When it was my turn the casher did not give and when I asked, she said the usual "no have". On walking away i saw the chap behind me, who was Thai who by miracle got his stamps and no more "no have".

The other day I purchased some stuff in my local 7-11, one or two of the items had the bonus stamp promotion, while at the counter the girl motioned/hinted if I wanted stamps, I said in Thai "yes, my son likes the stamps", she gave double what I would normally get.  7-11 girls are cute...555.
