I am on the side of the phamacist. The woman should have got all the phone before she reached the counter.
I was on a bus the other day when a young woman got on while texting. Instead of giving the driver her money straight away she expected him to wait until she finished her message. He told her off and she got all snotty about it. When she sat down next to friend a couple of seats behind me I heard her complain to her friend how rude the driver had been.
