i remember when i went to chiles with my friends, they told us we would wait for 15 mins. and like an HOUR and 15 mins, they apologized and sat us... then they gave us free chips (which most places give FREE anyways, and were like 3 bucks there)... not the BEST "im sorry" gift, but we werent too mad.
we just had a lot of time to talk =], and it was fun just chillin LOL
