Suitable reward?

[BringOnTheScience]

Long story short - lost my big bunch of keys. Handed in by local 6th former. Much relief & gratitude.

I have their name. Do I send a reward via the college? Amazon voucher? How much? Something else?

My son when he was a teenager found a phone on the way to school and the lady who's phone it was, was over the moon as it had the only photos of her engagement on there and no back up.

She insisted on giving him £25.

£10 amazon voucher would be much appreciated I'm sure.

Thanks! Will get one sent c/o college.

Keys had clearly been driven over. This teen saved them from getting utterly minced!
