I had this issue with my MacBook Pro in the apartment I lived in back in the early 2010's, but never had the issue since, so I always assumed it was some grounding issue.

The same thing happened in the Apple store I went to visit. Devices tend to zap you when you touch them. Maybe the problem is localized to certain regions?

Turns out to be a grounding issue--it reliably does/doesn't do it depending on location.
