I've got three things to say about Starbucks/chains.
1) I can't stand their coffee. If one isn't overly artisanal or fussy, most of the time, you would say coffee is simple enough it can't be screwed up. Starbucks manages that.
2)Their treats/baked goods aren't that good and they are over priced for what they are.
3)I don't know why we even allow endlessly large chains, if one is a free market capitalist, never mind an appeciator of variety in life, allowing any one chain to dominate, as Starbucks does, does not serve society's best interest.
Whether we cap market share, or set a saturation limit (no more than 'x' stores per 100km2) I'm for more variety. Especially so if Starbucks is what we are diversifying from.
