LOL, I know the feeling about scary interpreters I had my share with one of them during my pregnancy doctor's visits.
What happen was I was there on time she was running late, then she arrived about 15-20 mins later and said she had another apportionment earlier and it went late, So It was fine, then we went in the exam room and she started going through her purse and grabbed a bag of chips and started eating, and then the dr. came in and she was signing and chips were flying all over the place, Then she started picking them off the floor and eating the chips that were on the floor.
