Evening or early morning is a real decision
The default in most office cleaning is the evening, and for a general office that is usually right. A trade counter is different because the gap between the evening clean and the morning opening includes an overnight period, and anything that settles or is disturbed in that time is visible to the first customer. Entry glass and floors are the usual casualties.
Early morning work reverses that but brings its own constraints. It needs an access arrangement that works before staff arrive, it puts a hard finish time on the visit with no room to run over, and it requires a cleaner who can reliably be on site at that hour. Neither option is automatically better, which is why it deserves a decision rather than a default.
