I entered the convenience store and the associate (5'4" Female, long brown hair, no glasses, early 20's) at the register greeted me with, "Good morning!" I returned her greeting by asking, "What do you have that is more diverse than Brisk iced tea?" Her blank stare indicated to me that she was clearly hearing impaired, so I repeated my query by both shouting it verbally as loudly as I could while simultaneously using American Sign Language. The clerk shifted back a few inches, and with a look of her concern on her face, she placed one hand beneath the counter, still not speaking. I stood staring at her for her for a full minute waiting for her to reply, but finally realized that her awkward silence and the sweat forming on her brow indicated embarrassment on her part for working at a convenience store that carried nothing more diverse than Brisk iced tea, so I proceeded to the cooler and procured what the clerk had silently confirmed to be the most diverse item, a 97 cents bottle of Brisk iced tea.
I stepped toward the counter and the clerk made excellent eye contact. In fact she never once took her eyes off of me during my entire time in the store. Wordlessly she conducted the transaction, accepting my cash payment, making proper change from the register, and providing a receipt without my request. Although she did not smile at all, her dexterity was notable as she did all this with one hand while the other remained beneath the counter.
In consideration of her hearing impairment I signed and screamed, "Thanks!" The clerk immediately moved her free hand to beneath the counter as well, her weight shifted forward, feet shoulder length apart, with one foot slightly more forward than the other and pointing toward your me. I waited fifteen seconds, never breaking eye contact with her, as a small rivulet of sweat wound its way from her brow around her left eye. As she clearly was going to extend no expression of farewell other than her intent gaze and focused body language, I tipped my tin foil hat to her and then signed/screamed, "Have a nice day!" The clerk flinched but did not reply. I departed.
The associate did not ask for or offer a rewards card. She did not offer a credit card application.
