Today is December 20th, a very busy day for the post office in Smithtown. I was there at 12.50pm
One half of the front door was locked, so people coming in with packages and leaving had to get through the same 1/2 door. I asked the person at the passport office if they could open the other door and he said to me : We are closing in 1/2 hour. Brilliant

Staff is fantastic in both Smithtown & Kings Park too. People should not just comment for negative reasons, right? I've found the staff to be very considerate & helpful for at least a couple of decades and I'm just sorry I didn't comment much earlier.
