Staff member who *****

I went to jet Southgate mall today to buy clothes for my boys..they are twins so whatever I buy I make sure it's set. So Maria the cashier was very nice to me then I paid she packed everything in the bag everything was fine then when I was about to go our alarm rang to notify that there is a tag inside the plastic then a man who is a staff member at jet said he wants to check then he find out that they didn't remove tag on the Jean then he said I must go bag to the till so that they can assist me I said give me the whole plastic but he said no then I came back with the Jean put inside the plastic drive back home so when I was checking clothes I realized that the man who was helping me stole one item am worried about other customers who won't check their item
