I still use cash for all of my in-person purchases, but I do live in a rural area where cash is still king and you will get discounts for cash because the people can't just ignore the 3-4% markup on credit like more well off communities.

Also if you need to carry more than just a drivers license and a single credit card for your job. Trailers have their own registrations that you don't want people to loosely throw in their pockets, different professions have license requirements you need to have on you, receipts and notes are still important because you don't want to just be giving everyone your personal bank statements with cryptic "Part/product 482302" and no breakdown on the individual charges involved. Same with auctions and stockyards. Also someones phone on a job is way more likely to get lost/dropped/stolen and you don't want all your identification and licensing and registrations and receipts being lost along with your phone, you basically throw away the entire next day or two or more re-obtaining all that and like they say, don't put all your eggs in one basket.
