On repeated occasions, the two were allowed inside even after claiming they were unable to pay the $3 guest fee, she said.
This behavior sounds familiar - Atta and his buddies at the strip club. The biggest thing the waitress remembered was how cheap they were. Probably just a coincidence.
If you don't want to be remembered, you don't leave no tip, still less a 1 cent tip.
Speaking of the 1 cent tip, Muhammad and Malvo were staying at an Econo Lodge across the street from the gas station of their shooting at Fredericksburg (having stayed at the Ramada Inn next door the previous night.) News reports the day after the shooting said police were checking the motels in the area. Presumably they must have seen the pair at that point.
Lots of dates in this article. The Oct. 1 sighting in Fairfax is new. This is probably the pair returning to the D.C. area after their trip down south to Alabama, Louisiana, and Mississippi. If so, they sure didn't waste time starting their sniping spree.
