Mr. Grumpy Gills!

Well, if your job was being one of the seven dwarfs, I don't see a problem with that.

Grumpy Cat approves.

Attitude is extremely important in most jobs, and critical in customer service. Being grumpy with the customers is a valid reason for dismissal, and you will get fired again until you change your attitude. YDI squared. Funny thing too, according to research, holding a grumpy expression actually makes you unhappy - and a smile, even a fake smile, will make you feel happier. So you are doing a disservice even to yourself by being grumpy. Now that being said, some of the older women develop wrinkles around their mouths that make them look grumpy similar to Tard the Grumpy Cat; if that's your case, - well, FYL; maybe you can learn to hold some expression on your face that would counter that if you still want to work with people, because people do get taken aback being treated with grumpiness....

Depending on where you work, looking grumpy can be bad. if you work where you encounter a lot of costumers, looking grumpy can give them the wrong impression, which is bad for the company

I get that it might not look good in front of customers, but they at least could have told you first before firing you directly.

Hey there Mr. Grumpy Gills^____^

It could be bad for business...but I don't think they can fire you for that without giving you a warning first.

Did you not get a new year kiss from your ONE? COME ON cheer up

Sorry OP that sucks, same thing almost happened to my sister. she got warned first though. does your boss have a boss you can talk to?
