Are you sure you didn't push her Bohemian?
I know what you mean, those floors get very slippery. Forget the chica, I almost fell on my ass a couple of times, especially if the chica didn't dry off completely and leaves water on the floor.
I,m pretty sure the hotel lobby will believe your story, as there must have been a few cases like that happening? If not, you can always bribe your way out of most situations in TJ, or run like OC Hobby says. Maybe a good idea is PM Sampson and ask him a number to a good Tijuana lawyer, you can put on your phone, just in case?
If your really worried about it Bohemian get a chica who doesn't like to shower, before or after a session. You should have no problems there, the problems is finding the chicas that like to shower, and rarely do I find a chica that likes to shower first. I know maybe one at Hong Kong, that use to shower first, and insist that you shower too before starting a session with her.
If you ask me, I always get a chance with a girl who likes to shower. For me the problem I worry about, is when I turn the girl over for doggie from behind, that I won't get that strong whiff of ass smell, and that goes double if I engage in DATY and her pussy stinks.
