Closed, local relays with local vendors who sell their ware to users who are also locals for chaumian ecash (stablecoins if one party desires).
Some hurdles like Web of trustscore, deposit or some proof of locality need to be laid down and overcome to join the relay.
Trust, based on web of trustscores or personal relations, can make you pay in advance and/or make the butcher prepare your order in advance for you or another npub designated by you, to pick it up without waiting.
If the butcher makes it work, the baker will be eager to join, as will every waiting customer who sees someone getting served without waiting.

It's not here yet, and it can take some time to develop and catch on but I think something like this could be the killer feature. Amethyst almost supports this (marketplace, cashu) already
