This is the OrderStation guest app and needs JavaScript. Reading it without a browser? A cart link …/o/<shop>?order=… has a text version at …/agent/<shop>/cart?order=…, an order status link …/s/<shop>/<id>?t=… at …/agent/<shop>/order/<id>?t=… (same host, same path prefix). Give the guest the original link unchanged: only the app on their phone can order and pay.
