Sorry for the late reaction, this topic slipped my attention and I didn’t realise there was a reaction already.
I actually picked up a box of shake once but too be honest it was a bit of a weird experience, walking in on the office and flagging down the first staff member I saw, doing a transaction on the spot because there wasn’t a pin terminal on premise…
Have you actually considered an ‘aardappelautomaat’ outside like you see at some farms? Then you can just go up, beeb boob select the product and pay with nfc and you’re on the way, as fast as at a febo.
And for local delivery within the ring, depending on how much you sell within Amsterdam itself but it might be worth to have your own bakfiets for Amsterdam. Low cost, green delivery and an opportunity to advertise while doing it.
