Its nice to know that I wasnt the only one treated in such a way, I was starting to think they had something against me! lol.
Im sorry you have also received such ill service, I understand how frustrating it is.
Alistair, I do understand the difficulties with grand openings and the like, and how things can go wrong, etc. I have worked in events myself previously, however I feel the issue is more to do with how things are handled by the staff, and how complaints are dealt with, when a customer informs you that their credit card got misplaced and in a very polite manner as well, not even acknowledging the comment is rather impolite and demonstrates poor customer service. A simple apology would have been more than sufficient.
Good luck with everything.
