I've been trying to figure out what the team dynamic is here...as in, what sort of workplace context is this discussion taking place in??!!
I worked foir many years in a school with a staffroom with both a sink and photocopier, later on it even had a dishwasher.
So not an impossible combination of actions.
Just wondering why is it "I will do..." but not "if you WILL do...".
Can you also say --if you will do the dishes?
