Fuel consumption after hitting curb, please help !

Hi, I recently accidentally hit a curb recently and 2 tyres went flat, it was icy and the car hit the curb. Th alignment is fixed, and I don’t notice any issues with the car. I was wondering, would having the alignment done / hitting the curb impact the fuel consumption? My FIL is a mechanic/engineer and he thinks not as there don’t seem to be any issues with the car, but I wanted to come here for reassurance. The car has done about 40 miles less than it usually does but I was wondering if it’s just bad traffic? It’s a 2014 Ford fiesta, only has about 35,000 miles. 1.2L and manual :)

Please help, thank you!
