Shell Carlswald - Petrol attendant Thomas

I went to buy a cylinder and it didn’t fit on my heater, went back to ask for help as I thought maybe the size was incorrect. Thomas who assisted me found it funny that I struggled to put in the cylinder on my heater, he just stood there and laughed at me. He then said I must bring the heater for him to insert it, WOW!! I am truly disappointed…. What a waste of time and my petrol.
