DEAR ABBY: I read your column every day and appreciate the forum you provide for people to reach a large audience in an objective and effective way. I witnessed something the other day that could cause financial harm, and I feel your readers should be warned to be more careful.
My family had lunch in a busy fast-food restaurant. Seated at a table next to us was a gentleman conducting business over his cell phone. Since the restaurant was busy and loud, he raised his voice to be heard on the phone. Abby, he gave his credit card number, the expiration date, the name on the credit card and which credit card he was using! Anyone could have written that information down and used it for his or her own purposes.
Please warn your readers to be careful about giving out private information where it can be overheard. -- CONCERNED IN ANAHEIM
DEAR CONCERNED: Consider them warned. A lapse of judgment like that can wreak havoc on one's financial history. Readers, beware -- you never know who might be listening.
