I said usually..because service is meh a lot of times.ive done 15%+ plenty of times in the ones I go to more often that I know serve well and actually ask if I need anything, refills, how the food was ,etc....there's just plenty of places that do shitty service. 
  
 Sorry but idgaf about what's the standard rule of tipping. All you did was bring me water and plate of food. I'm not a needy person constantly barking to servers for different shit.

Are you in the US? May be different in your region but these days 10% is a bad tip. The rule I live by (after working in a restaurant) is 15% for meh service, 20% for good service. I only leave 10% if I had a bad experience.
