Tip no one the first few minutes you get off the bus, what happens is they break your arm to take up your luggage to your room, expect a tip then you never see them again,
they do not even work in the hotel most of them. so just smile and tell them tomorrow you will tip them as you have no money tonight.
tip the regular workers in the hotels, they are on as little as £2 per day. Its heart breaking, even the estate agent we now know personally was only on £60.00 per month,
makes you feel ashamed when you come back home and see all the waste here.
If its your first time in Bulgaria, you will want back as soon as possible. best place I have been and hope to move there if possible
