Customers doing your job, in your case, would be pretty annoying I guess! Not something I have to cope with in my job, thankfully.

I think you raise some interesting points – Assuming the person is there then I will pretty much always fill up others cups (unless the kettle is running low in which case I’ll fill it up) – I tend to underfill assuming that they can put in milk/water etc as required, or tell me to stop when it reaches enough for them. I’ll leave cups alone as they may not want a cup of tea. More annoying is when someone empties the kettle and doesn’t refill it (a 30 second job which just makes life nicer)

To be completey honest – I tend to find it annoying when customers try and help me do my job – normally because their wrong and it puts me off my train of though having them going on in your ear about the security settings (suprise suprise) when it could be their connection etc… No that didn’t happen today! ;)
