I know you can only buy 2 packets of paracetamol at a time but yesterday I put 2 packets of ibuprofen & 2 packets of paracetamol on the belt & the cashier only allowed me to buy 1 of each. Ibuprofen are anti inflammatory so not the same as paracetamol. Was the cashier wrong? I work on a till & would let someone buy what I was trying to buy.
