Florence Butt founded a winner. It has made quite a mark catering to Hispanics over the years. It's a good chain. Money making business.
They cater even more so now that one of the Butt kids married a Mex gal.
HEB has LOTS of connections, business wise in Mexico. They are tied in with the grocery supply down there too.
I can't say I see everything they do as an improvement, since I've been a long time customer and seen the trinkets scale up, and the die hard, high quality grocery/meat/produce that brought them to the dance to begin with, perhaps fade a bit.
I see it as changing of the control to the later generation of Butts.
