Ok be honest.
DD (18) and I just got into huge fight over what I said to the check out lady.
I just brought a months worth of meat and few other groceries, including a 2ltr of cold juice. The checkout operator put the juice, butter,and ham (from the deli) in the same bag as two trays of raw chicken (that were leaky). I very calmly said "umm what done here is dangerous, putting raw chicken with drinks and food that you don't cook. It can cause food poisoning and could kill unborn babies." I am obversely pregnant. The checkout said nothing. My dd went off at me for saying anything at all. She hates confrontations. I had to unpacked the groceries and repack them.
So is it unreasonable to except that your cold drink isn't put into the same bag as leaky raw chicken packets.
