Dear Employer,

If you do not want complaints of long lines, please hire a second person to help the 3-11 shift where your customers do not have to be served by 1 person only and try to keep the place clean and finish all the prep work. As the only person working there, I can only do so many orders at the same time and cash them out before moving on to the next person, especially if there are more than one sub per person.
Thanks.
