I found a new shop and the location is pretty good. However, it is a 1/4 mile from my current shop. Anybody ever went to a new shop that was in direct competition with their old shop? Any issues?

Im in the process of doing the same thing,ive been working in the same shop for 18yrs and the boss is a dickhead so starting my own business fairly close to where i work now.The majourity of the customers ive accumalated over the years are loyal to me so business will be good.It really pissed the owner and his son off but there is not much they can do about it..
