Their self service machines don't shout at you like the ones in Morrisons. I'm constantly reverting back to a 9 year old boy and saying sorry, and I'm not sure what for! I sometimes go out to my car and have a cry and then look in the mirror and tell myself "you're better than this graham, get it together!" And turn my self help audiobook on that's entitled "how to deal with self service robot machines shouting instructions at you, and why you shouldn't let it drag you down". After 45 mins of that, I finally feel confident enough to drive home; but then I realise I've used all my tissues and have to go back into Morrisons and the cycle begins again! Please send help!
