No stock of displayed items

I went to Mica Eastgate yesterday and saw a display of several mosaics. On enquiry I was told that they no longer stocked them, When I asked why I got shrugged at. When I asked a manager why they were displaying stock that they no longer carried his first response was to tell me that it wasn't his responsibility because he was in charge of electrical. He then told me that the displays belonged to the supplier and they can't touch them. No apology just bad attitude. When I asked why he didn't just remove the display from the shop floor he said that they won't risk damaging the display and that he had been asking the supplier for months to remove it. Now all of a sudden he does have some responsibility. So he was either lying about it not being his responsibility or he was lying about asking the supplier to remove it. Either way its annoying and unprofessional. The manager was rude and his supplier problems are his not mine. Mica should take responsibility for their stores instead of pretending that their incompetence and bad attitude are somebody else's fault.
