I went to this store to purchase caps that cover the 5 gallon water bottles for my water dispenser. On the shelf it said that free cap with fill or twenty five cents/cap. Because I live out of town, I usually get anywhere from $5-10 worth. I have been getting my caps here for the last five years. So today should have been no different. I went in asked for a bag to put all of my caps in and then proceeded to pay for them. I informed the cashier that I had $8.00 worth and he did not know how to put it into the cash register. He played around for a couple of minutes trying to figure it out. He then informed me that he would have to charge me more because he could not get it even to $8.00. I told him (Dave) that I noticed that he was able to get it to $7.50 and that I would take two caps out. He then said he would have to count all of the caps in the bag which I agreed to. He asked if I was a Shell employee and I said no. He then proceeded to tell me that they never sell caps like this and I told him that I had been coming to this particular store for the last five years simply to buy the caps. He looks to his partner and looks for confirmation and the guy says that I have never been there on his shift. I then turn to them and say ""what I am liar?" He then told me that I could not have bought the caps from him because his partner said I had never been there. I was apaulled to at him and told him that I just wanted to pay for my caps so I could leave. He told me to get out and that he would not be selling me any caps, as I had insulted him. I told him that he was the one being insulting by insinuating that I was a liar and called him a jerk. I asked to speak to the manager and he stated that he Dave was the manager. I asked to speak to his boss and he said that he was the boss. I am now trying to get a hold of someone in Shell Canada to file a formal complaint as he told me that if I did not get out then he would call the cops. All this over some water bottle caps. I do not recommend you go to this gas station because if they don't recognise you then you may not get served.
