<human>: Hello.

I started a job at a restaurant three months ago. I work full time hours there, and have worked at a restaurant before and know how to serve.

The majority of workers there are under 25 years, with the bosses (owners) over 30 years old. A wife and husband team own the place. 

Some backstory: I've had some issues with the full time bartender who is also a manager. She bullies me, bosses me around and has yelled at me infront of customers before. I talked to my female boss about it, and she said she had my back, that the girl was jealous because I threaten her job security. She said the plan was to become friendly with each other, so the bartender will lay off me and stop bullying me. She has, and I thought we were becoming friends or something (I am coming to the conclusion I am naive).

I'm a powerlifter/gym nut. I eat my oatmeal everday, I have visible muscle and get comments on my shape quite frequently from customers. I'm by no means a body builder, but I've got shapely arms, legs, ass the whole thing. 

Today I got called into the office and was given a talk. Word is, people feel uncomfortable working around me. My male boss told me "for such a small girl, you take up a lot of space. You walk around with your body puffed up like you own the place. People are scared of you. They call you Arnold and Hulk Hogan. You need to change, your job is in jeapardy."

I was honestly stunned. I think what he was trying to say is that sometimes I get thoughtless and don't yield to other workers (like at the coffee station etc). But he brought up all this teasing that is going on and I don't know how to move forward. Everyone is so friendly to me. I'm actually a nice person, I try to make small talk and be chummy and fun.

How do I move forward? I was really upset when my boss was speaking to me, because he kept bringing up all the shit people say behind my back.

<bot>: Getting teased behind my back because of my shape/demeanour at work. Not sure how much I am able to change and am looking for feedback.
