The man who sat beside me

[Bassim]

I am wondering if my sentence sounds natural.

The man who sat beside me on a bench took out a bottle and asked me if I wanted a shot.

 

[GoesStation]

I'd expect him to get out a shot glass as well if he mentioned a "shot".

 

[Rover_KE]

He'd be more likely to offer you a slug.*

*slug - a shot of liquor taken neat (Random House Dictionary of American English).

 

[SoothingDave]

Or a hit.
