I came in on 2018 and a girl helped me but I never got a card or correspondence with her name on it. I saw that SNAP must be helped after a certain age from DHS on Chad Drive to DHS downtown. The letters sent to me says ET and a number. Is that her? him? How cryptic is this? Prior to that, at Chad Drive, I always knew who that person was.
