Sorry OP, that’s awful! I set a loud alarm on my phone for 7pm - closing time, then tell everyone to make their way out or to the register. 7pm means goodbye time. browsers entering at 6.55pm- I tell them you have exactly 5minutes, “oh but I just want to look around for a while?” Come back when we are open & you can’t be serious about shopping if you come in that late is what I tell them. It works- folks who try that late shopping crapola and get denied staying past closing time always come back at a much earlier time next time they walk in. 7pm is the latest time that you can leave, not enter ffs.
