Absolutely do it.
Wear a suit regardless of the job.
Be very polite to the receptionist, they’re the first hurdle and their opinion is valued.
Whenever I got a call from “downstairs” about a walk-in first thing I asked: would you want him working here?
If it was a no, I’d walk down, take the resume and put it on the no-hire pile.
If they said he’s friendly and respectful I’d make time to at least have a brief interview.
Receptionists tend to be very good judges of character.
Do not..I repeat do NOT under any circumstance flirt with them as you’re waiting.
