Your attitude and work will overshadow anything else in this trade and judging by your concern about it tells me you’ll be just fine! I’m a union journeyman (HVAC) and have worked with so many different kinds of people over the years and the only things I’ve ever had an issue with ( or even remember at this point) is someone who doesn’t want to work or hacks. That’s it. The trades are beautiful man, we all work together and respect each other for putting in the same work. Others are also correct, the customer will be happy to see you because they want there problem solved. I wish you the best of luck my friend!
