In the sentence "来一瓶啤酒", what does the word "来" mean? I guess, it means "to bring". But I couldn't find this meaning for the word "来" in the MDBG dictionary.
来 come --> deliver --> serve --> bring
来一瓶啤酒 (come --> deliver --> serve --> bring me a bottle of beer)
The subject in 来一瓶啤酒 is the person listening to this order (e.g. waiter) and the verb 来 (come) is basically a short version of 送過來
(送過)來一瓶啤酒 = 送一瓶啤酒過來 - deliver/ bring me a bottle of beer
'来' still means 'come', but it can be extended to 'deliver' and from 'deliver' extend to 'bring'
Similarly: 上 (forward) --> deliver --> serve -->bring
e.g. 再上主菜 (then bring me the main course)
