Sleep well. The lounge and mini-bar may keep calling you, but you're not on holiday: others due at the breakfast meeting might have a quiet night in.
Be fair with tips. Reward staff for pleasant and efficient service and save something for the little extras - such as when the concierge is spot-on with their restaurant recommendation.
Know who's around. Sharing your table at breakfast could lead to a new deal. But don't drop your guard - the bar-hugger lapping up your jokes may be interested in more than just your wit.
Remember where you're staying. When taking clients back for drinks, you don't want to be peering through the cab window with the meter ticking on as you mutter: 'I'm sure the hotel's here somewhere'.
Limit your perks. Take the pen with the name of the hotel on it (see above), but draw the line at plundering branded bathrobes and towels.
Only beginners consider this valuable booty.
Watch your habits. Mini-bar beers add up, smoking in your room makes it a stale hell for the next poor soul. And, boys, no matter how dull the rolling news network, don't stray onto pay-per-view. A bill that includes Supple Secretaries makes for an awkward expense claim.
