We've had a few customers that have shown real interest in the POS system because they are small business owners too, and split their time between the register and everything else they have to do behind the counter.
I've started coding it only 5 days before opening, and it's paired with a kitchen app that shows & prints the orders, recipes, etc. They're both very raw and I'm working on v2 right now.
Definitely a space worth exploring. I understand the needs of bartenders, baristas, etc. a lot better now that I'm behind the counter.
