The fear remains that the penny will finally drop with Scottish football supporters when it's too late.
In the aftermath of Ryan Christie's decisive the Celtic away support let off two firecrackers, the noise from one prompting St Mirren's goalkeeper Vaclav Hladky to crouch down stunned holding his right ear.
Neil Lennon branded the flashbangs needless and without purpose.

The din took the sheen off what should have been Christie's big night. Celtic's march to an eighth successive title always feels easier with the midfielder in the team.

Defending his captain Neil Lennon insisted: 'It was totally accidental. He didn't mean it all.'
By the end of an underwhelming game of football Celtic found themselves two wins from the title. If events go their way this weekend it could even be sooner.
Lennon made four changes to the team which struck a huge psychological blow in the march towards the title. Dedryck Boyata's season is all but over, Jozo Simunovic returning to central defence as Emilio Izaguirre replaced Kieran Tierney.
