Though I still hate Dexit, I have found a place to use the remaining balance — the Pizza Pizza at the corner of Vic Park and Sheppard. Yes, their pizza is still like damp cardboard, but they have passable salads.
They still need to work on the reliability of their terminals, and training staff. The other day they said my debit was authorised, when clearly nothing had come off the tag. They wouldn’t take the cash I offered (their screen showed a green thing), so yay Dexit, free food!
