Currently in a family friendly restaurant. A mum has taken a toddler to the toilet leaving 2 children aged anywhere between 5 and 8, at a guess, sitting at the table. They are not being rowdy, they are not crying, they are just sitting quietly. But when a waitress came over with their food she got annoyed that they are alone and has left another staff member standing next to the table. So now they are sitting in awkward silence waiting for mum to return. Is it just me who thinks if mum is fine to leave the together, and they're not causing a disturbance, the staff should leave them alone?
