This lunchtime was in a large branch of Boots. Looked in chilled cabinet for pasta salad, saw assistant with 2 in her hand, prawn, just what I wanted - to my disbelief saw her tuck them behind the chilled drinks, making great show of pulling bottles to the front of the shelf, looking around shiftily. When she had moved on I took them out, even better they were marked down to 50p each! Whereupon she sprang back and said I couldn't buy them, she was keeping them for another customer who had 'gone to get some money'. Told her she couldn't do that, they're on the shelf and I'm buying them. She retreated. So I bought them, subsequently spoke to manager who was full of apologies. For me the markdown wasn't the issue, I would have bought them at full price but I was annoyed that the assistant had challenged me - don't believe a customer had to go and find £1 ffs! think she had them earmarked for herself.
