Same here, never had one ounce of problem with anyone in the club shop for years - and I go in quite a lot.
I was in there yesterday just to upgrade my Hull South Stand ticket - spent £ 2 but was treated with keen attention at a time when they are obviously busy / stressed, top quality service.
Perhaps returning shirts is not high on the priority at present - the throughput in the shop must have increased 100%
Great work Wolfware, keep it up, 2 weeks left - but it may all start again when we reach the Grand Final
