Extended family have been invited to a wedding , baby in our party will be nearly 1 . We found out from bride there will be no high chairs available. We contacted venue and they have agreed to now supply 3 high chairs .We told the bride , expecting her to let us have one of the high chairs as we had sorted but a few hours later she rang to say she’s allocated to other babies attending. AIBU to think as we sorted high chairs with venue we should be able to use one?
