For things that need to fit right like shoes or clothes, I much prefer shopping in person. I know online shopping has free returns/exchanges, but it’s a hassle to have to send stuff back, not to mention the time it takes. I only buy online if there really is no place in my area where it’s available.
For groceries, I definitely prefer to do everything in person. I like to select fresh produce myself. I’m also kinda picky in that I always take the second or third item on the shelf instead of the one in front. I also do not like my frozen/refrigerated groceries to be potentially sitting out in room temperature waiting for curb-side pickup or for delivery.
As for salespeople, I prefer not to be approached while I’m browsing lol. But yes it would be great if there’s someone available IF I ever need help. That’s rare though because when I’m looking to buy something, I do my research beforehand so I know what to look for and the purpose of being in the store is just to check it out in person.
