Waitressing is very stressful. I always had waitressing nightmares about too many tables and forgetting stuff. I still have them sometimes and I haven't waitressed for almost 20 years. It was my first job at 15, and I must have waitressed 6 or 7 different places in my young adult life. It does help if the meals are pricey and alcohol is served. I also read that if you insert the phrase, "for you" occasionally it increases tips. (Honestly! It was a scientific study!). Not for everyone, but a great temporary, seasonal, or second job.
