That does not match my experiences grocery shopping with women at all. Granted, I’m usually shopping with a control freak and there’s lengthy pre-shopping planning: organizing grocery lists, consolidating coupons, double checking sales, planning routes not just to the store to avoid traffic and optimize any side trips planned for the day but even a methodical path through the aisles to minimize time in the store. The actual shopping is over and done with as soon as possible, which makes sense because it’s just one of the many things that needs doing any given day and there’s always a dozen things that need doing after.
Now it might be different in rural areas where there’s really nothing else to do but while away the day but for working women - of which the majority of women I know have been - one more drawn out chore is not a leisure activity.
Clothing on the other hand is a different story. For a lot of the women I know that has actually counted as a leisure activity for them and the closest I’ve seen to the bahaviour described here though again speaking from my experience doing the shopping with a control freak there’s a good deal of pre-planning to that as well. I can’t say for certain but I suspect that some of the enjoyment when picking out something to wear comes from an element of anticipation: it’s a step towards future social interactions and leisure activities.
Alternatively the time taken might be less from enjoyment and more a combination of sharp awareness that a great deal is read into what women wear (whether it’s desired or not) necessitating a veritable war game session in preparation for assumed statements being made through clothing, predicting reactions to some outfits, how to respond, how to respond TO responses, anticipating the perception of social challenges and threats, how the various potential interpretations of multiple individuals can change an entire social dynamic and present future issues to manage, and just what kind of irrational idiot ideas other people might get in their heads, or how to deal with people simply assuming this is all being planned for when the only thing you were thinking is that you liked how it looked when you tried it on.
