Was the line at Earl of Sandwich during lunch time busy because of Free Dining?

Earl is always busy,I've gone in there 20 minutes before closing time,around 10:40pm and it had a good sized line.But as others have said even if you go in during lunch and see a huge line,make the line because you will be paying in 5 minutes and have your sandwiches in 10.I've now officially eaten at every Earl of Sandwich in Florida,DTD,International Plaza in Tampa,Wellington Green mall in Palm Beach county and the three plazas on the turnpike,which unfortunately don't have the full sandwich lineup.If the DTD location had a buy one sandwich get one free offer like the one in the mall at wellington green mall had when I went could you imagine the lines in there.
