Plastic hygiene

I went to buy pie and samosas and the lady who happened to be the cashier had to put all that i had purchased in a plastic bag dipped her finger in her mouth to make it moist so that she is able to open the plastic bag, i found this disgusting i told her not to put my food inside that plastic bag. Its unhygienic and other methods must be used to open plastics bags not saliva. <br> <br> her name tag was written Mercy Assistance
