How To Order @ Starbucks

We were invited by our Uncle and guests to have coffee at Starbucks after dinner. Now, if this was months ago, say 2 months since it opened, it would be almost impossible to enjoy it. Personally, I don't like Starbucks coffee 'coz it's too sour for me. It would take me more than 5 tablespoons to sweeten it up for a tall size brewed coffee. Anyways, who would protest to such an invitation? The place wasn't pack either since it was closing time.
