Unless they intercept the handshake as a proxy and have access to everything after that. The average Starbucks employee is not doing this.
An Israeli spy tracking down an arms dealer might figure out how to do this at a hotel the target was using, but the arms dealer would know that.
Edit: I think some vps would notice this happening, fwiw.
Hence “won’t happen at Starbucks, might if Mossad is after you”. Thanks for adding the details. I feel like most people think vpns are magic but also radically overestimate their personal risk.
