Brand loyalty undone

In South Africa as, I am sure, in the rest of the world the larger chain stores try to build brand loyalty by giving out cards to their customers on favourable terms so that they will shop in their, as opposed to their competitors, stores. This seems to work pretty well in general although every now an again things go a bit pear shaped as shown by the sign on the counter of a woolies store.



I wonder how many times the cashier had to explain that, no, woolies cards are not accepted here and, yes, it is a woolies store and no, it doesn't make any sense and yes, the guys at head office don't know what they are doing.
