Common courtesy is a matter of opinion actually. Some people tip, some don't. Some people hold the door open, some don't. Couldn't careless who does what.
Where I live it is illegal to ride on sidewalks in the city and pretty much only self centered a**holes don't tip.
etiquette
1. (Sociology) the customs or rules governing behaviour regarded as correct or acceptable in social or official life
2. (Sociology) a conventional but unwritten code of practice followed by members of any of certain professions or groups
So actually it is not a matter of opinion. If you fail to follow common courtesy you are intentionally being self centered because as you say you "couldn't care less".
