OK ATC made a mistake and it isn't best practice.However there might not be another suitable area to put a Cessna,especiallly when that traffic may delay departures.Then pilots moan about that.
I can think of an Airport (PD) that would grind to a halt,if ATC couldn't use exits to hold at well down the runway.This a combination of old WW2 layout,little investment in taxiways,and the airport operator leasing out areas which makes taxiing to these areas a one way system.
ATC would be trying to tell the pilot who is obviously braking hard for the first taxiway,take the 2nd.I have seen a controller get moaned at for doing this at a ''critical time''.Also ATC have told pilots take the second exit,and then they take the first.Then they are head-to head with a 10 ton helicopter.
Mind you the airport didn't have Rapid Exit Taxiways,despite ATC requesting one over 30 years ago.
