No entrance with your helmet at Builder Warehouse.

Took a ride on my motorcycle to Builders Warehouse at Southgate. So I am refused entrance by the security guard because I'm carrying my helmet in my hand and the sign on the door shows no helmets. I'm expected to leave my helmet on a table that looks like it's made of old pallets right by the door. Will they replace my helmet if someone walks by and *****s my helmet? Is my money any different from when I'm driving a car?<br> If they had a cage where I could lock up my helmet and keep the key with me, then I will abide by their rules.
