My DM and DF do this, I'll call them and they tell me that they're happy I called etc. Then the crunching noises will happen, my DF eating a bag of crisps whilst talking to me on the phone! I ask him to stop but he ignores it and I admit I have hung up on him before because I couldn't bare to listen to it anymore.
Next my DM drinking and not just a sip she has a whole glass and all I hear is 'gulp gulp gulp...' it gives me the rage but they don't listen, every time it's either crunching or gulping.
I can't be the only one who wants to scream at this?
