I have been to the Colindale Asda for over 20 years. Today I went to pay at the self service section. When, I finished it wanted verification that I am over 18. I went to ask a lady called Yoga to help me. She was the rudest person that I have ever dealt with in a shop. I was told that she could not do it as she worked 3 metres away. She then started to tell me to go away in the most aggressive manner. She then proceeded to tell me that she didn't care if I felt she was rude. I tried to complain to another member of staff who then told me to complain online. I will never visit this store again. Terrible customer service
