Unopened restaurant has stern warning for anyone thinking of soliciting, loitering, littering, etc.

For reasons unknown to even me, I've been keeping an eye on 424 E. 9th St. between First Avenue and Avenue A. The Moroccan-themed Sintir is planning on opening here...(The owners were denied a beer/wine license in February ... there is opposition from members of the Block Association concerned about the possibility of live music here...)



Work continues at the space... and check out this warning on the front window....



Is that stern warning so necessary?
