Couldn't afford much, so I bought mine some coffee, he'd been nicking mine all the way through the course, and gave him a (rather posh) automatic pencil I'd been using on my navlogs, he kept asking where he could get one.
Hi
Desipilot! You were one of the best instructors I ever had, good job you know what it's like to be on a budget, couldn't afford to give you anything but my thanks for helping me when things weren't going well - it was all worth it!
