Further to my previous remarks about St. Margaret's Bus Station, it appears that the situation is only getting worse with even more Flixbus departures vying for space in the bus station. Yesterday afternoon, I arrived at the bus station from Coalville just in time to witness FOUR Flixbuses trying to use the bus station at once.
Stand SA, used by holiday coaches as mentioned previously, was occupied by a Daish's coach; stand SB, the only bay in the bus station allocated to Flixbus, was being used by a service 087 Flixbus from Plymouth to Nottingham, while a service 079 Flixbus to Manchester was waiting in a layover stand behind, unable to obtain a bay for itself to begin its own journey from.
Within minutes of my arrival, a service 900 Flixbus from Nottingham to Gatwick and a terminating service 005 from London also turned up at the bus station: with no free bays for coaches at that end of the bus station, they were forced to pull into the next two bays, stand SC (used by the Arriva service 127) and stand SD (used by the Skyline Derby service) respectively. The two coaches left before any conflicting buses turned up, but after they left, the 079 coach then moved across into stand SC. Not very long afterwards, a service 127 bus turned up; after an irritated honk of the horn from that bus, the driver reluctantly drove it into stand SD instead.
These incidents played out over a space of about twenty minutes.
