It sounds you have had a lot of fun even though it was quite tight, but it is usually, when dinner before celebration where the parents of awarded people invited then they all try to come sometimes like you mentioned people have their grandparents who also want to be there and of course if there were so many waitresses that also contributed to the movements in such a small space. I can imagine that they were also a bit stressed. Seeing that little kitchen I would not volunteer to work in there. But luckily you have had a nice evening and nice company :)
