The answer from the observation of scenes is that they are. Because very often they are dull and the same thing always happens. Here's some typical examples...
A I'd like to buy loaf of bread.
B Here's one. That'll be 2 euros please.
A That's too much.
B Then you can't have it.
A I don't want it now.
A leaves
As people learn to accept more, it doesn't really help.
A I'd like to buy loaf of bread.
B Here's one. That'll be 2 euros please.
A There you go. Thank you.
A leaves

There's a great exercise to help stop transaction scenes being purely transactional. Actor A makes a "bland" or "transactional" offer and B has to respond to by making it personal (i.e. have an established relationship with the other player and/or emotional). Examples...
Recognition of other character (relationship and hopefully emotion):
A I'd like to buy loaf of bread.
B Is that you Simon?
Regular customer (relationship and hopefully emotion):
A I'd like to buy loaf of bread.
B Well, of course, Mrs Habersham. I've got the usual all ready.
Emotional (not about other character, although the other character will probably become involved):
A I'd like to buy loaf of bread.
B Thank you for coming to help. But there's no way we can save the shop. I'll give you this loaf for free – it's the last one I'll ever make.
Relationship and emotion:
A I'd like to buy loaf of bread.
B (suggestive) Of course. Let me get you a nice firm one.
Relationship and emotion:
A I'd like to buy loaf of bread.
B Don't pretend you don't know me, Daphne.
So a transaction is not inherently bad, but it's a trap for inexperienced improvisers who don't want to make the scene about character, relationships and emotions.
And although the characters knowing each other certainly helps, this is not necessary as long as there is some sort of connection or attitude to each other. Two people who have just met who have a strong connection or clear attitude to each other can make for an interesting scene. This can be positive attitudes: They are attracted to each other or instantly really enjoy each other's company; even negative: they antagonise each other from the word go; or a mixture: A is suspicious of B who is trying hard to please A.) If Daphne has to go into the shop of her bitter ex-husband because it's the only place to get the medicine for her mother – that's one interesting transaction. But two bland people in a nondescript shop trying to buy something neither of them cares about – that is highly unlikely to make a great scene.
PS Whilst the Dead Parrot sketch is based around the premise of one of the characters lying ("it's not dead, it's pining for the fjords") which is really very, very hard to do in improv, the scene works because of the attitudes of the characters to each other and the situation are clearly defined and heighten each other. (John Cleese's annoyed insistence causes Michael Palin to lie which causes John Cleese to get more annoyed.) It's also an argument scene which transgresses another rule, but more on that can of worms another day.
