I reserved a limo for tomorrow night and I vaguely remember the gentlemen telling me they would be charging my card 24 hours in advance. I can't remember just what he said, but I do remember it would be slightly more than the total. it showed up today, and it's 30% more. I guess they refund that after the fact? It has nothing to do with a gratuity does it? I plan to handle that with cash at the time of service. I am so ready to get out of here but my mind is MUSH!!
