Security was not well managed this time as there was an airport authority meeting so various people were prioritised over and above families already waiting to put bags through. I had an obviously upset (and less obviously unwell) child but still the belongings of meeting folk were pushed before ours by airport staff. One tray was held back as no one or sign indicated that all plastic liquids bags should be in separate trays so I recommend you add a sticker to trays, out signs up and tell staff to tell people as various people did the same which held up lots of people and your staff unnecessarily as it could have been easily avoided
