How hard can it be ?

This weekend I bought a T-Shirt from Sports Direct in Morecambe ( no Im not going chav ) and was very pleased with the quality , and it fit well which is always  problematic for me . Anyway I thought I'd better buy a second one while I was there ( 60 mile round journey ) but there was a snag  . The assistant told me that they only stock one T-Shirt of each size and that's only replaced once its sold . The replacement would come in four days time ?! This is a very large company that is a famous success story despite the economic times , and they don't have two identical T-Shirts in the same size for sale ? I guess its called efficiency , and I could understand this on a small market stall holder who had a tight turnover  , but from a multi million pound high street giant ? I was flabber ghasted !!!  Times must indeed be hard .
