Maybe a bit of an odd one but...
Would you think it's okay to walk into a solicitors office and expect to see a solicitor there and then?
I think this is ridiculous and that you should make appointments if you want to discuss something of a legal nature with a solicitor and my friend thinks it's perfectly fine and no one would understand to do otherwise.
I don't think I'd ever just walk into something like a solicitors office, accountants office etc... And expect to be seen without at least calling ahead.
Friend says it's not like a GP because everyone knows you have to make an appointment there so unless it's specifically pointed out, most people will think it's fine to do so.
