What's that cup doing there?

One day last week I went to the office bathroom and noticed that a big plastic Taco Bell cup was sitting on the toilet paper dispenser in one of the stalls. No lid, appeared to be empty. The sight seemed odd at first, but then it occurred to me that someone had probably brought it in with them to use as a tabo.

Yes, I have heard of the tabo. It's not something I use, but it's not a foreign concept to me either. Thing is, this is the first time I've seen that at the office, and quite a few Filipinas have worked here over the years (I'm only part, so I'm not counting myself).

...It just hit me that I've been with this company in one form or another for nearly ten years. That frightens me a bit.
