I understand the measurements in place but as far as I was aware I could remove my mask just to eat and drink. I was confronted by a member of staff who was really rude about me not wearing a mask when I politely replied that I saw no signs about food or drink when I was walking in (plus the staff member on the door said absolutely nothing to me as I walked in with food) and replied that I did not know about the rules in the store but was so rude about it. When I left I was looking for signs about food and drink in store and another staff member point them out on the wall that was completely out of view from the front door. Terrible experience
