XMas Tipping for a Building Manager

[clevernonsense.livejournal.com]

So, in the past year I've had 3 rather "serious" requests of my building manager (including one plumbing issue where I attempted to fix it on my own but only made it worse and he never made a peep about it). In each case he responded the same day I called. He even never answers the phone and always lets his machine field the calls (which my social anxiety when asking for help appreciates). So, for the first time in my life I really want to give my building manager a card with a holiday card+tip. The max I can handle is $50, but I'd prefer $25. So my question is just this: is $25 kind of cheap? I could include a note mentioning that I'm in grad school and $$ is somewhat tight, but the truth is I make a comfortable living, am going to carry a small manageable cc debt into June anyhow when I'm done with school and should get a hefty raise....

So, just asking for general thoughts.

cheers,
