Got blamed because I didn't want to go close to a stranger

[Cultural differences? Or is it more socially acceptable to be forced to do something when someone else (who could be a stranger) says so?]

Let me try to write this story out and hope it makes sense.

I was helping my mom close her store. An older man in his late 50s waved at me to come close to him. We were about 5 meters apart. It's not that far. I can hear what he's saying. I didn't need to go closer to him to hear what he has to say.

He waved and said, "come here, I have something to ask".

I said, "you can talk from there, I can hear you." In a neutral tone, even though he was much older than me. I guess I was supposed to speak in a nicer tone because he is older, but I had a long day at work, and I didn't want to have a conversation.

He responded, "I'm just calling you to come close to me, so I can ask you a question. Why are you so scared?".

My mom might have heard my tone of speaking and showed up and talked to him more nicely.

I was a bit pissed that he said I was scared of him. I wasn't scared of him. I just didn't want to go closer to him. I usually don't like being physically too close to anyone. I like being at a distance from another person. Unless they are my friends or someone I feel comfortable near. And still, I enjoy being at a distance so we can chat and it doesn't feel too crowded.

Anyway, this guy just had a question about some clothes he wants to buy. So my mom was able to show him what she has in the store.

This incident made me think of why he dared to call me to come closer to him, as a stranger, and when I didn't want to, he claimed that I was scared of him.

It is already disrespectful to order a stranger to do something for you, let alone blame them for not doing it if they don't feel like it.

I thought it was human nature to understand that. But wow. Humans surprise me still.

Anyway, I guess I need to continue standing up for myself.

At that time, even though I did feel that I was speaking a bit rude to him as he is older than me, I was a bit proud of myself for not just listening to his order/request to go closer to him so he can ask a question. I didn't feel comfortable.

Maybe I'm guarded a bit, but I guess I need to continue learning about myself on that.
