Sometimes servers will be really cool and have a conversation with you, or make jokes, or be really charismatic, or go out of their way to figure out what kind of food you can eat if you have a weird allergy, and be really nice and obviously wanting to be helpful. They can please a difficult family member who generally complains about everything, or make great food suggestions based off what you say you like. There's a lot of stuff a server can do to go out of their way to stand out. Are you saying you've never had a server where you thought to yourself after you leave "wow, that guy was great."? (also I think some places aren't allowed to, or can't put pitchers on tables, so just ask for 2 waters for yourself if you drink a lot of water and don't want to be bugged)
