Don't know if I'm overreacting or not, probably am but it happened last night and I have history of some abuse. I was in a tesco stored at around 8pm, I wanted to ask about an item so approached two customer service people at the checkout area, one was male and one female. I approached them both but due to how they were standing I was closer to the male so showed him my phone. He gave me this aggressive blank stare and shrugged but kept staring right at me, he made me feel really uncomfortable and just didn't say anything. A really cold stare. The female noticed I was a little uncomfortable so quickly came across to help me but would you complain to tesco about this? Am I being ridiculous. He just made me feel so uneasy.
