Human nature, there are pricks everywhere.

A tip, when botany gets busy, move down the beach a few hundred metres, and practise in a quieter area.
Launch the kite and get straight out on the water, plenty of people want to mow the lawn right upto to the beach and do their tricks, which causes congestion as people are launching as well.
Launch kite, and keep out the back, if you are struggling to keep up wind, and are still doing the walk of shame, use your judgment, whether you should land your kite first, tqo avoid congestion.
