Do people actually consciously make a judgement about quality of service when they tip??!

I always just mindlessly add 15-20%. So the whole "tipping incentivizes quality of service" argument has always seemed unrealistic to me.

I worked food service in the US for nearly 20 yrs. Most states there pay their servers and other “tipped” employees the federal minimum tipped wage which is 2.13 per hour. All your taxes come out of that. You also have to tip out other staff from your earnings (busboys, hosts, bartenders) based on your total sales etc.. 
because of this I never tip less than 20% unless I know the state has imposed a higher minimum wage for tipped employees (California and Nevada for instance both have a higher minimum wage) and then I would tip 15% minimum. 
If im a regular somewhere or if the service is very good I add to that minimum.
