Poor customer service!!!

This has happened at two stores now; the crescent, and la lucia mall: I ask the butchery for 4 cuts of rump steak, but to trim the fat off. A simple request, but they have no initiative because they say they cannot trim the fat off. I explain that they can weigh it first so I'll pay for the fat, but they are still lost? Then I ask if they can marinade it, and the answer, after 2 minutes of bewilderment, is NO, they cannot. How does pick n pay compete in the butchery department? There is NO customer service!??!
