Based on the limited information provided, it's challenging to definitively determine whether the customer is interested or not. However, her response of "you 2, I'll probably be back later this week" does not show much enthusiasm or engagement in continuing the conversation. She didn't make an effort to carry the conversation forward or reciprocate the niceties.
There could be several reasons for her response:
Lack of interest: She might not be interested in pursuing anything beyond a casual interaction at the bar.
Shyness or hesitation: Some people may be shy or hesitant to engage in conversations with strangers, especially if they are not used to giving out their numbers.
Politeness: She could be trying to respond politely but not show further interest.
Existing commitments: She might genuinely be busy and not have the time or energy to engage in a conversation at that moment.
It's important not to jump to conclusions based solely on one response. If you're genuinely interested in getting to know her better, you could try giving her some space and time. If she is interested, she might initiate further conversation or be more responsive in the future. However, it's also essential to be respectful of her boundaries and not push for more if she seems disinterested or unresponsive.
Remember, not everyone you meet will be interested in pursuing a romantic or personal connection, and that's perfectly normal. As a bartender, maintaining a friendly and professional demeanor is crucial, and it's essential to respect customers' boundaries and preferences.
