When clients book online they don't always add gratuity, so we still need to check them out when they are through. It should be required for them to add gratuity or they can click no gratuity but note that they will have to leave it in cash or not at all. We are trying to be hands free and it has been impossible. They should also be an option to tip assistants when they are booking. If this can't be done, we would love a checkout station for clients where they do not need assistance to checkout. I've asked about this before, but a receptionist would have to set it up for them. We want them to be able to do it without assistance so we can all stay safe and hands free.
