We might do the QR for customers that did not order using the app on their phone. We're printing stickers anyway, using the Star Micronics SDK which makes QR code printing a breeze.
Gotta say, love seeing the 'hack on my own rig' mentality applied to coffee shops. Curious to know how your culture views to-go orders? Based on the YouTube short (place looks awesome btw), I don't think the vibe is grab and go - but if it is, how are you handling the tickets? Just a separate Star for the togos? Nice getting that working, too - I'm stuck in a regional rep loop trying to get access to ours.
Roughly half of the customers do head out as soon as the order is ready, especially in the morning.
We print stickers regardless of to-stay or to-go because it helps us keep track of fulfilled items, and you can easily pass a sticker to a colleague if you need help with an order.
