Shell UK Ltd in Menai Bridge

Got a telling off here today for wearing my crash helmet to pay for fuel while in the shop. Ok, fair enough, when I told the cashier sorry, next time I will go to the window and pay through the hatch to be told I also must remove helmet to pay there. Do people of different religions etc have to remove head scarves and burkas to enter the shop and forecourt or is it just motorcyclist? Between my works van and two cars in the household we spend around £150 to £180 pound a week at this garage on fuel alone without other items, as I told the cashier its was my last visit here today for good, plenty of other welcoming garages in the area.
