I wouldn’t be worried you’re having an affair, I’d be worried you’re contemplating a sex change. Browsing? Sitting in coffee shops? Taking ‘any’ time to go shopping when the internet serves that purpose? You are becoming a woman.
Bloke shopping, when not conducted by the internet, involves
1/ Identification of need: I need a new shirt
2/ Specification of need: 16″ neck, long sleeve, white
3/ Identification of where to buy: M&S, maybe Next as a fall back
4/ With SAS snatch squad precision: enter M&S, locate item, pay and depart in as short a timescale as possible being seen by the minimum of people.
5/ Go home safe in the knowledge that you have shopping as a fine art.
