As far as I know, same here. The only thing I do is grab a ground lug from a electrical outlet before handling chips and boards. Which may be superstition and ineffective. I may be doing the right thing or I may be using up my luck and one day fry something expensive.
I doubt this is doing anything. Static electricity is the difference in latent charge between two things, and if neither of those things is attached the the actual ground, touching the mains ground (which is attached to the actual ground) isn’t doing much.
