Unfortunately for Mellow Yellow purposes,
International Waffle Day (March 24) was on
a Wednesday this year. These waffles are Belgian,
but IWD originated in Sweden.
("God dag, Sven—let's have some waffles and
celebrate the end of that long, dark
winter!") So if you figured out where this
truck would be (that day, it was parked on
46th Street between 5th and 6th Aves.) and you wore
something yellow, they'd give you one
free waffle. Nice PR, eh?
