It's hard not to get frustrated with a bad experience and it's hard not to take it out on the person who is the business's representative (the service person). I'm not making an excuse, you should be kind to everyone, but it's hard to get punched in the face and turn to the puncher and say "I'm sorry but did you mean to punch me in the face because I don't think I deserved to be punched. Are you having a bad day?" instead of "F you!" Sure, bad service is not a punch in the face but it is in the same category of receiving something you shouldn't have received and don't deserve. And, where do you draw the line on what's mean? I can be kind to the service person but then go leave a bad review on the restaurant. Isn't that also being unkind to people? (or maybe it's being kind to others, warning them against bad experiences). That said, I do see people in the USA (not sure about other countries) that act entitiled. Example, they spill something an instead of cleaning it up they think "not my job. Someone is paid to clean here so no need to clean the mess I made". Even if it's just bussing your own table in a fast food place where it's clearly expected you're supposed to clean up after yourself lots of people will just leave their trash at the table with a "not my problem" attitude.
