hmm archer emiya + shopping
Well if weāre talking mundane groceries naturally heās a pro. He knows how to bargain hunt and pick the best ingredients and peers at the marketing of big companies because heās suspicious that theyāre screwing the world over, thus buys a lot of locally farmed stuff to be a local hero
If weāre looking at object shopping, you can bet your butt he knows the nearest hardware store inside out and pulls a Ron Swanson āI know more than youā when assistants try to show him around. Ditto electronics (heās very disgruntled to come back to the past and have to search through all our primitive technology)
Clothes shopping, though, he is E rank at. Rin drags him around to make sure heās professionally and nicely dressed, because otherwise he would still own three versions of the same shirt, one pair of jeans and a jacket. Some things never change
