i had that experienced once before sa ayala na nadakpan ko sa No U-Turn (kay ni U-Turn jud lagi), and the guard was very civil about it. i talked with him and pleaded that i didn't see the sign (which was true) and so after a few minutes of negotiating, he let me go with a warning only. i think not all of them are a-holes man siguro. naa sad tingali mga arrogante pero dili sad tanan.
