This is identifying but I don't care.
So a work colleague was complaining that her computer was running really slow to which another colleague piped up:
'paint it black it will run faster'. Then everyone burst into fits of laughter and it was forgotten. This colleague does like to have a joke at work but it good at the job.
Locality manager didn't seem to have any issues and didn't mention anything. I'm sure it's forgotten within the office. Everyone working here is White British. Luckily a Nigerian colleague was on a visit at the time.
Would you be concerned by this joke. Would you discipline the employee? I would certainly have at least called him into the office but let locality manager take the lead as he was in the room too.
