I used to work in event management and definitely this couple are CF. But, big but, the changes made in their order should have been confirmed in an email like my example below so there is no uncertainty. Anything said in person, or over the phone needs to be followed up in an email, so no misunderstandings can occur;
Dear CF’rs.
As discussed items from your initial order are no unavailable, so will they be replaced with XYZ.
The cost of food is now £££
Total cost of event £££.
- please see updated event sheet with your coatings and timings and let me know if you have any amendments or queries.
Every change, all the timings, need to be on an event sheet, that the client has signed off on each time a change is made.
Whilst the hotel is doing what they can to recoup costs, going too far tarnishes their brand, making potential good clients put off by immature behaviour and also just making them seem a bit scummy. For sure name and shame, but full on trolling no. Does too much damage to the venue long term.
