I do wonder what would happen if Thailand ran out of paper.
Today, I picked up some steak at Makro. Two labels on it, a price for chicken ( cheaper ) and a price for beef. The checkout chick scanned the chicken label, even though the steak was clearly visible.
Stopped at the door, wrong price paid on the receipt. One form generated to refund my money, give back the steak. Then another receipt after I paid the correct amount.
20 minutes of faffing around. Just as well I didn't buy ice cream.
