I see no inconsistencies.
One is a dialogue, which is always presented like this, regardless of British/American English:
English yelled, 'I will strangle you for not giving me that 0.5 points!'
One is a quote in a narrative:
Once upon a time, I yelled at Mitch for 'not giving me that 0.5 points', because he's just a big meanie!
(British English)
To my understanding, in the latter situation, American English would present it as such:
Once upon a time, I yelled at Mitch for 'not giving me that 0.5 points,' because he's just a big meanie!
So, yeah... I see no inconsistencies.
