I am very confused at this... So, please tell me something. If my Mum, myself and my 18 month daughter, go to have something to eat in, say, John Lewis cafe, or a cafe/ restaurant of some sort, you expect us all to stand, queuing, in a long, hot line, for mum to then pay, and carry the tray over because i'm pushing a buggy or carrying my daughter?
Why is it unreasonable for me and DD to get a table, sit her in a highchair, and wait for mum to come to us with a tray of hot food/ drinks ?
I really really don't understand this... Yes, its annoying if you cannot sit down, but you can't get angry at other customers who are sitting waiting for someone to return with food/drinks. infact, its ridiculous to expect a group of people to all stand in line until the person paying has done so, then all traipse off looking for a table.
Maybe, possibly, i could understand getting irked by someone on their own going and putting down bags etc to save a seat ready for returning with tray... a little... but not a great deal i'm afraid.
Answer is, to not go into such places that are so busy, or find somewhere that has a sign telling you not to sit down util food purchased. Even then, such establishments would have trouble having a go at anyone in the situation i've described with my mum and us...
YABVU IMHO.
