All these trailride tales 
As a teen, I did a short stint as a guide for a livery stable.
With the other teens, one of our ideas of fun was when a rental rider asked their horse’s name.
We’d tell them things like Satan, Killer, Lightning… All of them nose-to- tail reliables.
Even though this was in the 60s, when we’d actually do some trotting & even {gasp!} cantering on rides.
Briefly, because inevitably someone clueless as to how to sit would ask for the faster gait, then last all of 5min before begging for us to slow down. 
DH & I, on a trip to SF, went for a ride in the Molera Ntl Forest with a local livery.
We’d both taken our well-worn schooling chaps & jod boots to wear & before the group was assigned horses, the guide asked if we rode.
We said yes, but not often on trails.
He complimented us on our “shotguns” - meaning the English Eq-style chaps.
I got a pretty chestnut mare & at one point in the ride we passed very close to a bobcat watching us from a log. Mare never flicked an ear.
I asked the guide how long they’d had her.
Answer: “Oh, about a week” 
So, I guess we’d told them we rode, without telling them we rode. 
@Renn_aissance Sounds fun… NOT!
On a London vacation, we also rode in Hyde Park out of Hyde Park Stables in Kensington.
They supplied both helmets & paddock boots.
IIRC, we weren’t asked about our level of experience.
DH got a 5yo Irish Draught, I got a large piebald pony. Just us & 2 young guides, W/T/C through the lovely park on great sand trails. To get there we rode through city streets.
Then there was my Swiss coworker, who came with other coworker friends to where I boarded.
He’d said he rode, but I put him on my TB, on the longe.
After about 5min, I took off the line, he obviously rode. And well.
He ended up taking the horse over a small course setup in the outdoor.
Such fun to see my horse, doing what he did so well, from the ground.
