I just wanted to drop you a quick line to thank you for the service that you provided for our conference last week. The team building exercise (‘marble run’) was well-received and certainly presented the teams with a challenge that required quick-thinking – and as your Instructor Ben commented, he witnessed some designs that he’d never seen the likes of before! Talking of Ben, can you thank him again for me please? He had just the right ‘touch’ and managed to keep the teams on track for quick turnarounds. I think we provided him with a few laughs along the way too!
