I have complained several times to customer services and Minnion managers about Tesco allowing irresponsible adults to be wheeled around the store sitting or standing up in their shopping trolleys. There seems to be no consideration given to the possibility that there may be animal shit, vomit residue or other contaminates on the child's shoes leaving the trolleys in an unhygienic state for the next user. But then I do not think that cleandness and hygiene are trade marks of the British. No matter I have found the more customer caring stores do no allow this practice, so my problem solved.
