I would never use a ATM on South Grand. For that matter, I would never be on South Grand for any reason. STL city is trying become like DeeTroit.....and full of 0DumboVoters too.
I rarely use ATMs at all anymore. I no longer carry much cash and if I need an extra $20, I'll select the "cash back" option at the supermarket checkout. On the very rare occasions I need a lot of cash, I'll go inside the bank. You're just too much of a target standing at an ATM machine (especially in certain parts of town).
