I don't think it does. Any sensible business avoids tax i.e., minimizes its tax bill. If it gets up to what are perceived as evident shenagans to do this, governments can change the law (as has been announced today in the UK) and consumers can decide if they still want to do business with the company. 'Don't drink their coffee' would be the advice re Starbucks, would it not? Good deals usually but not always add up to good business which equates with making more money. If Starbucks offer a lousy deal then presumably they'll either have to change the deal or go down. Plenty of other places to drink coffee.
