Stop in for a cup of coffee

Watching the final round of the British Open. They are playing at St Andrews known as the home of golf. Playing there is on our bucket list.
We went to our club last night and played a round of golf. Our first 18-hole round in three years.
We used to play a lot doing couples golf tournament all over the Midwest.
We quit for many reasons cars, buying a house, etc...
Hardly anyone on the course last night and we zipped right through.
It's one of the most difficult courses in the state tight fairways, lots of trees and elevated greens.
I shot a 79 and Cheryl an 86. For the non-golfers here that ain't too bad.
Like riding a bike.
Again forgive my ignorance of all things golf but what is a scratch golfer and do your scores make you that? You two want to go to Scotland I am in. We still have land there. Both sides of family are from there. I would skip the golf course portion but we love Scotland. Well I reckon I could carry your clubs for you, nominal fee of course!
