Gateway Mall Incredible Connection Rude Staff

I visited the Gateway Mall store and checked prices on a dvevice I wanted to purchase. Returned to the store at 18h45 to make the actual purchase and staff rudely shut the door in my face, refusing entry. Store closure time is 19h00 and even though I informed them that I'm flying out the next morning, staff member walked away.

Due to that treatment, the store won't ever see my money regardless how affordable they may be compared to a competitor.
