You'll never know what you don't know and how much it will cost you in the future as a result of not taking up Steve's offer Francis.
Having already been in the industry for ten years I travelled 2 hours to spend a day with Steve before buying my first TM some twenty plus years ago. You'd pick up and take in tons of stuff you just don't get on a training course. I mentioned this thread to an old friend in the business (who did all the carpets & floors on How clean is your house TV series for years so somewhat a veteran like me). He laughed and said "if Steve charged them two hundred quid to spend the day with him it'd be worth it, wouldn't it?"
With a half smile & raising of an eye brow I just said "there you go".
