I honestly don’t see the need to tip, they’re just driving you a few minutes and sometimes they don’t even pick up the bags since many are women. It’s got to be the easiest laidback job. People tip because they feel pressured to. That’s not a good reason. There’s so many jobs that make crap money that dont get tips. The only time I tip really is when they take you somewhere other than the airport. I feel like they’re actually serving you there. But the hotel route is their job.
