Short-Lived Relief
Once the people had finally thinned out and the rush was over, the stranger looked around before slowly walking up to the counter. She felt herself tense up, ready to press the button. She braced herself for whatever was about to happen. She almost visibly sighed and sagged with relief when she realized that he did only want to buy something, however. She knew the relief was plain as day as it washed over her face. Instead of something disastrous, it would be a plain transaction like any other. However, she had no clue about what was about to happen.
