Tipping a person for a service they provide is always up for speculation. Most often times a courtesy to the driver who picks you up to take you to the rental pickup locations are often tipped based on service performance. Of course this is all up to the person who is being picked up, as a tip is not mandatory.
The usual rules to follow are simple if you wish to tip and these are some of the signs that a tip is appreciated:
The driver is on time - When you ask for a service such as a driver picking you up, you expect them to be on time and prompt to your request.
The driver offers to help you with your bags - Drivers do not have to help you with your bags, but if they are heavy, they can help to reduce strain on your back by loading your luggage onto their vehicle.
The driver is very nice and helpful - Delightful drivers are very easy to get along with and they like to spark up interesting conversation to help pass time while you travel to the rental service.
The driver provides excellent driving skills - They are not falling asleep or driving erratically while on the road, do not speed and follow the rules of the road.
The driver does not ask for a tip - This is a major red flag if they do request a tip. Tips are a gratuity that is only offered if service was satisfactory. They would receive one without asking if they performed well.
It is not difficult to decide whether or not a driver deserves a tip. If you were unsatisfied with the service, save your money for someone else who deserves it!
