Sangria
Bartenders don’t like it when you order sangria because they usually need to make it on the spot. This means they have to cut-up fresh fruit and prep the drink when they get the order. Even worse is when someone orders two glasses, especially if they had already been warned to get a pitcher. This requires double the work and can make any good bartender’s face turn sour, so take their advice and get it by the pitcher to save your server the hassle.
