I would think that as Calis is a holiday area and most shopkeepers work long hours perhaps the Chemist would be open too to get the much needed business. I am sure that holiday makers who are staying in Calis and called at the Chemists in Calis would have no idea that there were chemists around the Hospital that may be open. Perhaps the Chemist should put a note on his window of the location of a duty chemist near the Hospital. I spoke to a regular visitor to Callis recently who did not even know we had a Hospital and had never been away from the sea front area. I know that some people call at Chemists for things like mozzie cream, headache tablets etc., not just for prescriptions.
We have always seen the Chemists in Hisaronu and Oludeniz open on a Saturday.
Yes, businesses want a day off, but not many businesses in Calis seem to have that luxury.
