You presented a scenario and I agreed with you - if you are out with say 4 people on a business dinner and picking up the tab then I don't think the tip should be out of your own pocket.
But if you are travelling solo and have the chance to enjoy a meal at a nice restaurant - and the receipt will be refunded to you - then I do believe you can at least cover the tip.
