St Andrews teacher trap advice

My St Andrews instructor - poured about 1/2 a 55 gal drum of balls in a trap and said 'see you in a few hours"
Also (at least my author) of the story - when I was complaining about the pot bunkers - "shouldn't hit it in there"
He connected my bitching with my 10 years in the US.
Another nice story - supposedly when Jack Nicklaus was playing a practice round -" is this an 8 iron?"
Caddy - "yes, if you hit it right"
Tough these Scots.
