Had a customer who had rushed off to work leaving the front door wide open, I called inside - no answer Checked with neighbours and had gone to work, so explained to neighbour the situation they returned with me, wrote a note, shut and locked the door.
Got a call that evening, very, very grateful 😃
3 month later we get a call from her, it was my birthday yesterday, treated myself to a window vac, don't come again... 😫
I would lock up, leave a note that keys are at number. Xyz - job done
Then expect to lose them 💩
