These machines are a pain to use. I tried one at Wawa. Put together my whole order but inexplicably it was cancelled while I was asking a question to an employee. So my choice was either to redo the whole order or walk. I walked.
The explanation: Took too long to enter something, so the machine reset the process as it could only assume you changed your mind about ordering and wandered off. Try it with an ATM and you’ll get the same thing. Most have a 15-30 second timeout.
The problem isn’t the *machine* here. :P
I think that’s probably a time-out problem. Did you let them know about it? That’s how they learn to adjust things like that. It’s how they learn. Much easier I’d think that with an illegal who’ll never assimilate and learn English.
