This is the way in Canada. Although several versions exist, the most common one (for me) goes like this:
Turn unit to customer -> OK -> Confirming amount $nnn. Add tip? -> Yes ($) / Yes (%) / No. --> Enter tip amount ($ / %) -> Confirm new amount OK --> Enter PIN (if card inserted) or tap card --> Approved, printing copies for client and merchant.
