Over a number of months I've seen many threads expressing horror at the idea of drinking or serving instant coffee. So….I've become a bit paranoid. So mners - if I have a mum in for a cup of tea/coffee when they pick up their dc from my house am I committing social harakiri serving up instant coffee if they opt for that instead of tea? If I want to have or keep friends should I be brewing/grinding/working out how to use the coffee machine etc with a flourish?
