Some problems with this advertisement for a pocket ashtray.
The top line reads: A green way to toss away your cigarette ashes. Make it cigarette ash, since the word ash is uncountable (hence singular) in the context of tobacco, wood, coal or volcanoes. The plural ashes is more appropriate for cremated bodies and for buildings, etc. destroyed by fire.
The next line reads: Your environmental friendly Pocket Ashtray. The compound adjective is more commonly environmentally friendly (adverb+adjective) or environment-friendly (with hyphen).
The last line is the exhortation, Don’t be a Tosser, keep the city clean! The word tosser is a bit unfortunate here since it is, among other things, a swear word with the literal meaning ‘one who pleasures himself’.
