I know it's been discussed before, but to add my two penn'orth:
Travelled to Manchester for a business meeting only to find on arrival it had been cancelled and no-one told me. So, a free day in a punters paradise, but...
As a slightly more mature chap I use some chemical assistance, BUT as this was all unplanned didn't have any blueys with me. So, called into Asda by the Trafford Centre to their pharmacy. Cute, quite sexy Muslim pharmacist saw me. She was busy administering flu jabs asked me what I needed, and she asked me to call back in 30 mins.
No problem, went and had a coffee.when I returned she showed me into the private consulting room, already carrying a bag with a box in it. Quick chat (quite fun talking about erections with a pretty Muslim lady) and 10 minutes later I'm leaving with 8 x 100mg sildenafil tablets for the bargain price of £22.
Well recommended!
