Taxying a C152 is easy enough but it's a bit harder than taxying a Tommie, I'm not sure I'd always let them to the taxying as quite often the brakes are a little squishy and the aircraft doesn't respond as fast as you would like it to
, also it depends what aerodrome they were at and how new the instructor was as well.
All sounds like a really good trial lesson and perhaps more of a debrief would have been warranted but what feedback can you give other than "how was it?" and "do you have any questions?" "When can I book you in for your next flight?"
MJ does have a habit of converting Trial Lessons into full courses though
