Nope, thankfully I was only in grade school in Oakville, Ontario back in '73. The name comes from a couple of friends of mine who helped me get the business started here on the island, they owned the famous but now closed Lagniappe Restaurant across from Fido's. Dan's roots are based in New Orleans hence the Cajun connection.

(LAN-yap)

n. Chiefly Southern Louisiana & Mississippi

A small gift given a customer by a merchant at the time of purchase; broadly: something given or obtained gratuitously or by way of good measure.

[Louisiana French, from American Spanish la Napa, the gift : la, the (from Latin illa, feminine of ille, that, the; see al-1 in Indo-European roots)+ ñapa (variant of yapa, gift, from Quechua, from yapay, to give more).]

"We picked up one excellent word" wrote Mark Twain in Life on the Mississippi (1883), "a word worth traveling to New Orleans to get; a nice limber, expressive, handy word --'lagniappe.'
