Arriving in US I have opened a bank account in a local bank and got a debit card. When paying in a restaurant I signed a check adding to the basic sum the sum of tips and outlining the total sum. But next day when I checked my bank account online I saw that only the basic sum was withdrawn from my account but not the total sum. When the tips will be withdrawn from my account? The question stays because when I will leave the US I will close my account, so if anybody want get these tips they should do it before long. On the other hand I don't want to cheat these restaurants I would like to provide them these tips. What are the options to sort it out?
