1. I hope Stephen Biko isn't your real name.

2. I hope you don't have a smartphone, or better yet I hope you only have a landline.

3. I hope you don't use social media at all.

4. I hope you only access the internet via multiple proxies, and only via an anonymous, sandboxed browser.

5. I hope your internet access is only via hard-wire, and that your house is shielded with a faraday cage.

I'm pretty careful about my privacy, but there are much more pressing concerns than having the quickie lube shop be able to pull up my service history. I don't share my phone number or email with said companies; all they have is a license plate & a vin...which, technically, is a matter of public record anyways.

Good luck!
