This 2pm to 5pm alcohol sale ban is the most strange rule I ever heard. How often have I been in Makro, BigC, Lotus, 7Eleven and wanted to buy some beer together with my normal shopping in the last 20 years? In between in Singapore and Malaysia for working where this afternoon sales ban not exist and then back in Thailand on my monthly home trip I stayed again in front of the locked Shelfs.
One time in Makro at 1:50pm at the cashier. One guy in front of me. During payment then he fished out a lot of coupons until 2:02pm. So I could bring back my beer. I was very amused
