Went in for breakfast after working all night. Sat down at a booth, viewed the menu and made call. This took me roughly about 15 mins. Within that time frame no one acknowledged me or so much as offered me a drink. I realize that it's a very busy time of day but someone could have at least made eye contact and said that they'll be right with me. So I left and went to Denny's where my food was half off.
