Should have just done it

Had a work event last week at Chicken n Pickle and ended up introducing myself and talking to a really cute waitress about her life in Kansas and her time at KU. I really wanted to ask her out after the event, but my deoderant had worn off and i reeked so i decided not too. Also she mentioned she was going back to Kansas in a week and so i did not know if she meant permanently or just to visit family.
I got a couple stares from her while i continued with my event and when she would walk by it seemed like she wanted to look at me but i kept my focus more on the event and did not press for her. Im thinking of going back next week on the day i was there a few weeks ago to see if she would like to grab drinks sometime as she seems like a cool girl to get to know more. I hope she is there when i go! But she says no, its no big deal ill have gotten out of my comfort zone and boosted my confidence regardless.
