There's absolutely [nothing clearly visible on their website](https://www.firstgroup.com/greater-glasgow/tickets/ticket-prices) that even mentions a £2.50 single. It just mentions singles as "from £1.70" without specifying why and whether the price rises. In a sane world it would be worth your while to complain to the operator about being intimidated by drivers or to the regulator about the opaque pricing structure. In reality the only thing worth doing is getting involved in the pressure group [Get Glasgow Moving](https://www.getglasgowmoving.org/) to get First kicked off the franchise and have SPT operate the buses again. |
