Lol... I can see this happening. One of my customers scared the bejus out of me last week in a similar way. She wanted a repair done to her watering system but I was out of the clamp I needed. She says I have some in the shed so in we go and she is rummaging through this tray asIi am looking for the bit I need. Well this little lizard takes off and she launches the tray and contents skywards and lets out this ear peircing scream that scares me. Made us both laugh.
