How do you know if the florist does not come with the floral table centerpieces missing half an hour for the event?

Reagire quickly and try to compose my own floral centerpieces of my garden of the hotel.

look for an alternative ASAP

I go and search for stored decoration owned by the hotel ( like what I did in one event ) Or I contact another near supplier by the hotel , I inform the client but I recalm him

How to get the other centerpieces when you have only30 minutes for the event?
