The Co-op in Oakengates, Telford

Why are the till staff who work in the mornings so hateful. I asked for a carrier bag and practically got it thrown at me. They never say hello..please or thank you..they think its an honour to be served by them..well! it isn't. I shop for a friend (who likes the co-op). me personally I'd rather stick hot irons in my eyes than set foot in oakengates co-op.. but because she's my friend, I do it for her. The afternoon staff are totally different. They are friendly and pleasant, lovely to speak to. Please get rid of morning till staff.
