I was in Waitrose Winchester on Saturday with my 17yr old daughter. I picked up a box of 4 bottled beers for my husband. At the checkout we had bagged all our goods but the guy on the till called the manager. He refused to sell me the alcohol because my 17yr old was stood next to me in the queue. I thought he was joking...apparently not. I told him the beer was not for her but he didn't believe me ...rude! Called me childish because I wouldn't buy the rest of the shopping. It seems that they are allowed to assume that I am buying alcohol 'by proxy' for her. Very embarrassing at the till. Has anyone else had this issue?
