His odd behavior hadn't really phased her much after he went and sat down. This was a homeless shelter, people acted odd all the time. So she continued her work, serving up drinks to go with the meal, though she would occasionally steal glances towards him. after about the fourth time looking over, she decided that she would get him a plate if he did not come back up on his own. 

But he did. And for his wait, the line was shorter. he got offers of food - rice, chicken gravy, stuffing, noodles, meatballs, and sandwiches. 
Once he was done with that part of the line, he would come to her - the drink lady. She smiled a bit when she saw him come to her, "Hello again. Would you like lemonade, water or gatorade?"
