I have to ask?
And yes I do realise that the person involved is not here to answer.

How is someone not buying a round for someone who is not present when the call is made (unless they've already told someone else their order or they've hit the bog/phone - in which case guess or apologise later) considered racist?

EDIT: I've had friends and workmates who missed out on a shout because they were on the phone/dunny and they were of all color, shape and proclivity. From memory all of them took it on the chin & no one called foul.

I believe it's referred to as "playing the race card"
The same member of staff has also accused another colleague of refusing to take her to the shops (during a shift) in the work vehicle because she was black.
