Bought a load of stuff in B&Q today and went to use the self-serve till foolishly assuming the 20% would be taken off by the system. No Siree. Everything went through at full price and when I queried it the assistant told me I had to 'request the discount from an assistant before I started'! What a con. I wonder how many people left the store assuming they had received a discount but hadn't? I went straight to customer services and returned everything and then re-bought it with the discount! Got to get up earlier than that to fool me!!
