There is an exit from the supermarket that requires you, the shopper, to climb up eight steps. On the left side of the eighth step is a pair of metal poles that are concreted into place and a rectangular red painted metal notice with white lettering is affixed to them. It instructs as follows:
"Trolleys will stop at this point". 
Just in case you were wondering, any trolley of mine would not have made it up the steps!
