It depends on the location and competition from other local businesses.
The Starbucks where my parents live is nice to sit down and have a conversation with someone - it's bigger and has more space. Why? It's a small town and there isn't much competition from other local coffee shops.
Compare that with the Starbucks's of Manhattan - usually very cramped, little seating, and meant to be more of a "to go" place than a place to sit down.
