Embarrassed in gas station

Last Saturday, an embarrassed thing was happened on me and my friend. We wandered around at night in Tainan by riding mtorcycle. The motorcycle almost ran out of gas, so we went to get some fuel in the gas station. The embarrassed thing was that we both didn’t bring any money and didn’t notice that until got the fuel. We were nervous because the worker looked at us and didin’t know how to do. Hence, my friend stayed there and I rode to home to take money. What embarrassed! This was my first time that went out without bringing any money in my pocket. Now, I will warn myself whether I bring money or not whenever I go out
