@jrafanie Regarding the rubocops

• The redundant self's are in the original code, and for my patch I continued that pattern so it was consistent.
• The is giving syntax errors because it's checking against Ruby 2.7 syntax, however that code is valid ruby 30 and 3.1 syntax. If I convert it to single-line method like def location; {}; end, then we'll get a rubocop error on not using the newer single-line method syntax. I just need to update the bot/settings to check ruby 3.0 syntax.
