Clearing a path through the supermarket jungle

Stopped by Albertsons and found my normal entrance (the main one, and the closest one to Rite Aid, so it's the one used by many seniors) roped off by rough string. Some paving work had recently been done in the parking lot, but parking was unrestricted and there was no immediately apparent reason for the door to be blocked. I thought the door was closed for some reason, but it was still functioning—people were just getting roped out of and inside the entrance area for no reason. When I left the store by the other door, I purposely walked back the length of the building, into the cordoned off section, waited for a 70ish year old couple to stare in confusion at the string before carefully bending under it, and then I walked up to a section, touched the blade of my Khukuri to it, and down went a section of string before I could even feel the blade contacting it. Immediately after, I saw customers and employees walking through my cut section, paying little attention to the remaining sections. Order was restored, confusion eliminated, and potential injury averted.
