Question

を at the end of the sentence?
What does を mean when it comes at the end of the sentence?
For example:
よい一日を。
お食事をご注文のお客様全員にアイスクリームを！

Answer

it is omission.
よい一日を（お過ごしください）。
お食事を御注文のお客様全員にアイスクリームを（サービスします）。
When we can expected after words,we omission it.
and,we can omission after "を".  を cannot omission.
(it is rule,so i cannot explain why.)
よい一日を。 is an idiomatic phrase,so usually, we don't say after を words.
