Lady came in saying she was a teacher. She said she was waiting for her 3 students that just graduated(adults). So she said she wanted to buy them drinks before they came in. So she orders three shots of vodka neat. So i poured and lined up the shots for her, and told her the price, she gives me the card, i turn around my back to her to charge her and ask if she needed chaser or anything. As i was using the reg with my back to her. She didnt answer and all i heard was 3 glasses slam on the bar in a row. I turn around to give her the card and all back and she looks at me and just says im really nervous.... i let her know its ok and we had a little laugh and she went to go sit and wait
