You ever noticed how all of Starbucks coffee tables are round? There's actually a really important reason behind this in her book. Grande Expectations Financial Journalist: Karen Blumenthal explains how round tables are more welcoming than those with square edges and people look less alone while seated at a round table, so customers are more willing to linger around in the store if they feel more comfortable.

That's because Starbucks wants us to feel comfortable but not too much at homes with the new customer can take our place once we finish our drink.

This is the perfect way to maximize Starbucks's profitability.
