I agree — I had an encounter with FBI way back in the mid 70’s- I had overheard a conversation from the booth behind my husband and I regarding robbing a bank/ with ski masks etc — only reason I noticed them at all was they ( all men) were harassing the young waitress including running their thumbs up her leg and more— she was polite but it caught my attention and I listened to their conversation— the next day a metro bank was robbed and I mentioned it to my husband who hadn’t paid any attention to their dialogue and he called local LEO’s that were friends of his — that evening 2 FBI agents knocked on our door — showed their badges as they introduced themselves ( 1 male/1 female) and we sat and discussed what I’d heard— they were well dressed and very professional— I realize times have changed but those guys definitely don’t look FBI legit unless the local agents have gone to crap along with the DC crew— she did exceptionally well —
