It's good (if unsurprising) that your daughter has found herself a part-time job.
I'm sure the £50 a week (plus tips) she's earning right now, will absolutely balance out the lack of proper long-term career opportunities resulting from the inevitable economic downturn we're heading for, and also entirely make up for the loss of her birth-right - of freedom to live and pursue her chosen career in 27 EU states.
I'm sure she's very grateful to you.
Waiting, bar work etc have always been part time, non career building, student type jobs so not sure what the "proper long-term career opportunities" has to do with it.
