I like how easy it is to create orders, add items/prices etc in this system as well all of our customers are able to see what we have available at any time! It can be hard sometimes when things change but that's just because everything changes quickly nowadays so you never know whats going around till its too late (eg no more burgers).
We haven't had an issue with owls yet which has been good & they've done some pretty cool stuff recently - including creating QR codes where people could pay by scanning them instead or using NFC chips built into their phones!!
