My local pharmacy, where I collect my prescriptions, is open Monday to Friday, 9 to 6pm, closed for lunch for an hour every day; the pharmacist (and owner) is only present three and a half days a week, which means we are unable to collect prescriptions on the remaining day and a half. Plus it takes about five days to process regular prescriptions.
The previous owner was open six days a week, and was nearly always available; the present owner has three other pharmacies and is clearly running it as a business venture on a shoestring; shop is poorly stocked but charges top prices for everything.
