Definitely a deal breaker

Imagine falling in love with someone and finding out they eat KitKats (Nestle).

Kit Kat is a chocolate bar created by Rowntree’s of York, England. It is produced globally by Nestlé (which acquired Rowntree’s in 1988),[1] except in the United States, where it is made under licence by the H. B. Reese Candy Company, a division of the Hershey Company (an agreement Rowntree’s first made with Hershey in 1970).[2]

I wonder how much that license cost Hershey.

No difference if Nestle is getting paid anything for the sale of KitKats in the US.
A lot, but they paid in four smaller installments and every year the cost is slightly smaller.
