This will kick off no doubt but hey. Slightly tongue in cheek.
Coffee shops on a Sunday morning should be a haven for adults who seek to get away in piece and quiet from every day life for an hour. That means getting away from your own children , DH etc 
So been here 5 mins , had to queue behind a mother with her toddler using the display of pastries like choosing sweets in a sweet shop ! Just pick up a croissant get your latte soya single shot and move along !
Then we have the child , mother and grandmother. The GM doing the exaggerated parenting in this case with the GC much to the horror of her own DD. Thankfully they've gone.
Piece and quiet now reins ....
