What do you do when someone's already on the lock landing?

What's the etiquette when a boat is on the lock landing for a lock you're about to go through? Presumably double mooring onto them will be a pain for them when they're about to set off either through the lock or the other way. Do you just bob about waiting if there's no more space on the landing?

To the guy on a bike who called me a 'stupid fucking cunt' at 8am on Tuesday morning

For not 'being behind the line' while waiting on my bike for the lights to change before turning onto Westminster Bridge, you are clearly deranged for screaming at strangers like that and I hope you had a horrible day. Was truly a horrible start to mine.
