Getting good service can be a difficult problem in our indecent, modern, world. One way of guaranteeing good service is to provide a cash tip to the person assisting you. In restaurants and in service bays where you are well-known, tipping helps get you good service; but what do you do with the incidental worker you may only see one time, like a moving company team, or a repairman? How can you make sure they’ll get the job done to your satisfaction within your time requirement window? Conditional Pre-Tipping is one method I use to ensure excellent, one-off, service.
