In CH the two queues are; EU/EEA/CH/diplomats and All passports. This implies than any of the first can go to the second. I honestly can't remember if there is equivalent signing at UK airports, or if says all 'other' passports. I'll have a closer look next time.
You perhaps could first of all apologise for being in the wrong queue and thank him/her profusely for allowing your transgression before they get a word in edgewise. And also promise never to post your experience on an aviation pilots forum.
