That's a whole other forum in itself - it applies to everything people find to talk about. "Well, of course, I never saw any -ism at work, maybe you took it out of context." etc.
I can cut them some slack with answering the phone - if one of them is with a customer who is noodling, and the other is in the office on the phone they may not notice it. If I was a customer in the shop and talking to the staff about something I'd be annoyed if they kept stopping to answer the phone.
I am still patiently awaiting the new website - mainly because when looking at pics of shiny things on my phone it is clunky to navigate.
