Task: Question Answering
Input (English): Context: Understandably , their move took longer than expected , so our dinner plans were pushed back until 8:00 pm . I knew there was so way I could wait to eat until then , so Mal and I grabbed a snack and a cocktail at Charley 's on Newbury Street . I was in the mood for a good , strong cocktail , so I ordered a dirty vodka martini . ( It was after 5 o'clock ! ). 
Question: What may be the reason they mention that it was after 5 o'clock ?
Output (English): That 's when it 's acceptable to drink .
