Everyone has manners, but do they use them is a different story?...I'm not saying give up your seat right now, but if someone does give up 'their' seat for 'you', at least have the respect to say thank you.
I always post my Steemit/Dtube videos on Youtube to help PROMOTE this blockchain!!....This is what I write in the description, "Youtubers :) you should sign up for Steemit.com or Dtube, it's free to signup. You get paid to do the same EXACT thing you are doing on Youtube. EVERYONE makes money, not just the people at the top. Even if you don't like to make quality posts, you can make money from UPvoting and Resteeming other users on the platfrom in the form of curation rewards... Give it a try my friends."
My advice is not good advice, let alone legal advice lol. Do your own research.
