So, what I could't appreciate is changing the flavor and then pretending it wasn't. Hah! Haven't bought any in a decade.(Correction: tried one bottle of the Mexican stuff. close; no cigar.)
In the non-"bottle bill" area of the US where I lived, the last time I remember bringing bottles back to the grocery was during the 1980's.
