I don't do it for everyday tips. But for the annual Christmas tips, yes. Like to the doormen or the parking garage valet. Anyone that would get a card, I think it's OK to put a check inside. But not for tipping the bellhop at a hotel. I think that would be weird. As for writing checks to people whose name you don't know (or in my case, there are certain doormen whose names I would surely misspell), you just write "Cash" on the name line.
