i was at Houston's in Georgetown years ago (i heard it's closed down now

) w/my two girlfriends in XYZ Sorority, Inc. our waitress was a soror who was still in undergrad. i chatted w/her and in the end, was ready to give her a nice tip since she did right by us. we got our bill and she didn't charge me for my meal. my girlfriends were not pleased but it worked for me
ah, Membership, it does have it's privilges...
ps. she definitely got that nice tip
