Come now, my friend, I struggle to comprehend your hesitation. What could possibly be amiss with a lady finding you attractive? I must confess, it is a rare occurrence for a lady to take the initiative and ask for your phone number. Typically, it is the other way around. However, it is not an everyday sight to witness a lady approaching a gentleman to request his phone number. Even in the context of a service provider, such a scenario is considered unusual. Whether she is a service provider or a regular woman, such instances do happen, although I concur with those who find it uncommon.Allow me to firmly adhere to the belief that there is a suitable match for every lady, just as there is for every gentleman, irrespective of one's physical appearance. It is possible that you may not perceive yourself as attractive, but rest assured, there is always someone out there who will find you captivating and appealing. I implore you to cultivate greater confidence in yourself. Life is not always filled with idyllic moments, but there is always that one person who will appreciate you for who you are. Regarding the specific situation at hand, I highly doubt the lady in question is a service provider. It is not customary for someone in that role to go out of their way, make a sudden turn, and enter a restaurant just to ask for your number. My recommendation is to embrace the flow of events and see where it leads you. In my personal opinion, her proactive approach in asking for your number is a strong indication of interest. Best of luck, my friend.
