I worked with Bob at TLS in the late 90's and for a short period he was my boss. Great guy and I remember at one sales conference in Coventry, late into the evening, we were chatting, with Bob having a glass of wine in one hand and the rest of the bottle in the other he went to lean against a wall that wasn't there, stumbled slightly, quickly regained his composure and continued the conversation without spilling a drop or missing a beat. RIP Bob.
