If you configure that hotspot name with WPA-PSK, it should not attempt to connect to hotspots with the same name that are not WPA-PSK. If the hotspot it tries to connect to does not have a matching PSK, it should fail the handshake (and no, the client isn't disclosing the PSK to anyone during the handshake). If any of this is not true, that would be another vulnerability. Also WPA-PSK is useless for coffee shops because you have to give the PSK to everyone, and with that the ability to impersonate the AP. For that purpose, EAP/TLS is better, assuming you take care to verify the AP's certificate.
