So the pharmacy now want my mobile number. These are the folk who shout customer's names and addresses across the shop each time a prescription is collected (or they invite customers to shout this information). Now they want my mobile number too so that, in the very rare event, if my prescription is ready and I've not been in for a few days they can contact me. These are the jokers who asked that customers rang a day or two before visiting so that they could make sure that the prescription was ready to collect - and they then found that they couldn't answer the phone because it was too busy. I don't imagine that they will be getting my mobile number any time soon.
