Unsealed box at UPS
I know I made a mistake. I had some important documents to send via UPS. Arriving at the store, I asked for their suggestions as the documents were thick. The UPS store person suggested me to get a UPS box. Later she generated a label and I put the documents inside the box. I asked her if anything else need to be done. She said NO and returned me the receipt with tracking number. I left the box unsealed thinking they would probably do it.
Now I got to understand that there is no guarantee they would do it because it is not their job, rather it is my responsibility. It happened yesterday before 7 pm right before the shop was closed. Today is Independence day, the shop is closed. The shop will open tomorrow at 12 pm. The current tracking status shows "Labels created".
What should I do? Should I go back to the shop to ensure sealing the package?
EDIT: I went to the UPS store today (the next day). They told me that as I bought the UPS box from the store, it is their responsibility to tape the box. I do not need to worry about this.
