Metro Grocery Store what a rude employee Oakville, Ontario

let me start this by saying that I was holding an umbrella and a bread with an intention of buying them, then me and my friend went to the magazine section. there was an old guy reading a couple of magazines there and then he left without buying any of it. me and my friend was looking through some magazines with an intention if any of it was good then we were going to buy it. they weren't just any random

magazine like fashion magazine or whatever, they are national geographic or photography magazine or new yorkers cartoon of the year (since we are art students, so we look at the art related stuffs). then an old lady who is an employee there coming to the stall near us and store some stuffs there. we were still looking and tried to find something interesting and she was suddenly said "this is not a library, if you want to buy the book just take it and pay it." we were so pissed since we didn't even read any of them. we were just looking through it and if the magazine is good then we will buy it. is something wrong with that? I saw many people just read them at the store and we personally never do that because we know that it is not right. I don't know if she acted like that because we are young and Asians or what. but i really don't like that kind of attitude. especially because she works in a grocery store, where you must respect your customers, and that's not how you are supposed to treat them, no matter what. except if they do something wrong and not permitted. we didn't even see any signs that says "opening or reading the magazine are not allowed." it was just disrespectful. too bad we didn't see her name so we can just

complaints to the store manager.
