Not the best professional use but I can see why they got angry. I think her complaint would have got taken a lot more seriously if she'd have gone through the proper channels instead of declaring it publicly on facebook.
I generally avoided parent meets such as these like the plague anyway but i definitely wouldn't have chosen this venue as my first choice anyway.
Wetherspoons here have it right. There is a separate family area. Where we always go and sit. I remember a bloke coming to the family area to do his work, so he could keep his laptop on charge, and he spent the whole time huffing and puffing in another family's direction who had a young baby. Couldn't help thinking that he would have been a lot more comfortable if he'd used the area designated for adults.
But flip it on it's side, you've paid £££ for the hotel, had x y and z to do. You come downstairs to get your notes ready for an upcoming and important business meeting and you've got that noise going on just a few yards away. Whether you intend for it to be or not, it is distracting.
This hotel seems to be like that, designated for Adults, and there is nothing discriminatory about choosing a different clientele for your business. Choosing to allow your paying residents to work/rest/hold meetings in peace is not against the law last time I checked.
Loving the mumtitlement! There's finally a word for it.
