You keep our small business busy, we’ll keep you on the road

BREAKING NEWS: THE BOSS HAS ACTUALLY BEEN SPOTTED DOING WORK.

We didn’t believe it either, so naturally we had to get photographic evidence. 📸

Turns out he does know how to use the tools… who knew? 🤷‍♀️😂

While we’ve got him down there, might as well remind everyone:

🛑 Squealing brakes?
🛑 Grinding?
🛑 Pedal feeling a bit ordinary?

Get your brakes checked before “she’ll be right” turns into “oh sh*t.” 😂
