Don't put your things down and forget about them. Keep contact with them, have one hand or one foot on them. Face the street rather than the phone so you can see around you. If two people on either side of you are talking to each other, be cautious. ATMS ATM robberies happen both during the daytime and evening hours.
Robberies are more likely to turn into rapes, kidnapping and murders at night.
Look around when you drive. If it's one you know you'll be using frequently, ask the bank its crime history. Do not use the same machine at the same time every day.
