The same, surely. They both do a decent cup of coffee, after all.
Yes, but Starbucks is one of those retail organisations often cited negatively by the anti globalisation / anti capitalist lobby. Others would include the big 4 supermarkets but especially Tesco (due to it's buying power and perceived ethics) and Asda (due to the Walmart ownership), McDonalds, KFC etc. There are definite strong connotations with a Starbucks arriving in your town.
It's striking how far this message has seeped into the consciousness of many. You hear lots of people saying 'I'd not like a Tesco/Asda in Marple but an Aldi or a Waitrose would be great'. I don't get it personally, nor do I care for expensive, fancy coffee - instant does me fine.
Anyway, we already have Britain's biggest retailer (by one measure) in Marple which is only a couple of doors down from Hanburys.
