Really bad attitude and treatment of customer

I ordered a mix of specific paint yesterday and ran in today to get it -was in a hurry - greetd the staff and was ignored and again greeted them and was told that they will get to me as soon as 2 others in front of me were served! I ran out and decided to not spend my money there and decided that it is not fair as they would not be able to use the paint for anybody else. Fetched it afternoon and made my being very unhappy clear and was told they do need need my attitude! Rude , unhelpfull cannot handle 3 clients in a shop to serve the public!!!!!!! I still paid fro the product - stupid as i am!
