Called the course the day before to make my tee time. Spoke with the gentleman and he clarified that if I booked the tee time it would be my slot. I followed through with that. With everything going on with covid not wanting to play golf with someone I don t know. Drove 45 minutes to the course this morning to be notified that I was paired with a 3some. Told the guy that is ridiculous because I spoke with him yesterday and he guaranteed me. The parking lot had 3 cars in it and nobody on the tee box, why couldn t I have just been let out then?
