Bad attitude

I went to Builders Warehouse to buy paint this afternoon and was helped by a super staff member by the name of Percy in the paint section. There were only 2 x 20lt left of the paint I needed and one of the drums was really badly damage, so Percy asked me to speak to the manager at Info as the goods were damaged. I went to Info and spoke to a Sydney Tshabalala who was more interested in his phone that assisting me. When I told him that Percy asked me to see him as the drum was damaged, he was immediately annoyed and called Percy on the intercom. Percy was busy with another customer so another staff member came to assist. Sydney started speaking in a language which I don't understand and it was a huge effort for him to actually assist me. He gave me a slip for a 5% discount, which is fine, but his attitude stinks. I wanted to bring this matter to light also because I don't want Percy to get into trouble for actually doing his job with efficiency and passion, only to be shot down by someone with such a bad attitude.
